Hardware Overview Important Overview This manual includes information on the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI, (MTS part number 100214316). For example information in this manual regarding shunt verification, zeroing procedures, or software utilities will pertain to the Low-Profile TI.
Spinning Applications (Test Track) Spinning Applications (Test Track) The SWIFT sensor can be used for road load data acquisition (RLDA) applications: • Durability • Noise, Vibration and Harshness (NVH) • Ride and Handling • Tire Performance The transducer is durable enough to withstand harsh road testing and data acquisition environments.
Non-spinning Applications (Simulation Lab) Non-spinning Applications (Simulation Lab) The SWIFT sensor can be fully integrated into the simulation process, since it is an optimal feedback transducer for use with MTS Remote Parameter Control® (RPC®) software. The transducer takes data at points where fixturing inputs are located rather than at traditional instrumentation points along the vehicle’s suspension.
Construction Construction The SWIFT sensor has one-piece construction for outstanding fatigue life, low hysteresis, and high stiffness. Its compact package has a minimal effect on inertia calculations, and a minimal dynamic effect on the test vehicle. The transducer can be used for developing conventional durability tests on the MTS Model 329 Road Simulator.
Construction Hub adapter The hub adapter attaches to the inner diameter of the transducer, allowing you to place it at the original position of the spindle face of the vehicle. The hub adapter enables you to maintain the original position of the tire on the vehicle while the transducer is attached to the vehicle (the tire will not protrude from the vehicle).
Construction The slip ring anti-rotate device should be configured such that no loading occurs to the slip ring throughout all loading and suspension travel. This means that when you attach the anti-rotate device to the vehicle, you must consider all possible motion of the suspension. The anti-rotate device should not bump against the wheel well at any time; any jarring of the anti-rotate arm will damage the slip ring.
Construction Transducer Interface (TI) The TI comes in two versions: a Low-Profile TI and the newer Mini TI. Information on the Low-Profile TI can be found in this manual. Information on the Mini TI can be found in a separate product manual (MTS part number 100214316).
Construction Design Features Flexure isolation The SWIFT sensor has a very stiff outer ring and flexured beam isolation which render it relatively insensitive to stiffness variations in matings with rims and road simulator fixtures. Flexure isolation minimizes thermal expansion stresses. With flexure isolation, if the inner hub experiences thermal expansion the beams are allowed to expand out, resulting in lower compressive stress on the beams.
Coordinate System Coordinate System In the transducer, independent strain gage bridges measure forces and moments about three orthogonal axes. The signals are amplified to reduce the signal-tonoise ratio. An encoder signal indicates angular position, which is used to convert raw force and moment data from the rotating transducer to a vehiclebased coordinate system. The force and moment and encoder information is sent to the transducer interface (TI).
Coordinate System The direction of positive forces follows the right hand rule: • Vertical force (Fz) is positive up • Lateral force (Fy) is positive out of the vehicle • Longitudinal force (Fx) is positive fore or aft of the vehicle depending on which side of the vehicle the SWIFT is mounted You can change to the MTS Model 329 Road Simulator convention (lateral load into the vehicle is always positive) or to any coordinate system by changing the polarities in the calibration file.

Calibration Calibration Important The following sections include information related to the LowProfile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI software utilities (MTS part number 100214316). Each transducer is calibrated by MTS before shipment. The transducer and LowProfile TI may be returned to MTS for repair and recalibration as required.
Calibration When you press the Shunt button, the associated Shunt LED lights. As the LowProfile TI automatically switches through the series of bridges, it verifies that the outputs are within the accepted tolerance range. If all bridge shunt values fall within the tolerance range, the Shunt LED on the front panel will go off (after several seconds). If any bridge fails to fall within the shunt tolerance range, the LED will blink, indicating that the shunt calibration has failed.
Low-Profile Transducer Interface Low-Profile Transducer Interface The Low-Profile TI performs cross talk compensation, transforms the loads from a rotating to a non-rotating coordinate system, and produces an analog output signal suitable for any data recorder.
Low-Profile Transducer Interface The Low-Profile TI transforms eight inputs (amplified bridge signals) into three forces and three moments by the following process: • Applying a zero offset and scaling the signals • Using a geometric matrix to transform the signals into three forces and three moments in the transducer reference frame • Using a cross-coupling matrix calculation to scale and sum the individual signals into each output • In spinning applications, using a rotational transformation to pu
Low-Profile Transducer Interface The angle output for a tire rotating at constant velocity can be represented by the following illustration: Angle Output 5V 1 rev = 360° 0 360° 0° q 360° S20-10 Although you may not routinely use it, the angle output information is available for tasks such as tire uniformity testing and troubleshooting. You may also calculate angular velocity by measuring the frequency of the angle output signal.

Power switch and Indicator The power switch turns power on and off. A green indicator will light to indicate that the Low-Profile TI power is turned on.
Low-Profile Transducer Interface Angle Zero and Bridge Zero switches These switches are used to zero the transducer inputs. Which switch you press depends on the ZeroAlgorithm that you specified in the calibration file (see following illustration). Two different methods are used to zero the system: spinning and non-spinning. For more detailed information on selecting a zero method, see the chapter, “Setting up the Transducer Interface.
Low-Profile Transducer Interface When a system zero is initiated, the associated LED is lit. After successful completion of the system zero, the LED turns off. If there is a failure during the system zero, the LED will flash at approximately a 1 Hz rate.

Low-Profile Transducer Interface Zero LEDs These indicators indicate the current state of the zero process. The ZeroAlgorithm value (0, 1, 3, or 4) you selected in the calibration file will determine the state of the indicators when you press either the Bridge Zero or the Angle Zero button. • The indicators are off under normal operating conditions • In non-spinning applications using ZeroAlgorithm=0 (required), press the Bridge Zero button.
Low-Profile Transducer Interface Address selector Each Low-Profile TI in a communications chain has a unique address. This address is used in every read or write command from the host computer. The host can transmit to only one Low-Profile TI at a time, using its assigned address. The Low-Profile TI will reply to the host when it has received a command. The address selector switch allows you to set the communication address for the Low-Profile TI.

Low-Profile Transducer Interface Low-Profile TI Jumpers The transducer interface uses circuit board jumpers to establish certain parameters and make use of various electronic functions. These jumpers are set at the factory, and should not be reset. The following table is for reference only. Jumper Setting X1 Function Excitation setup for shunts FX1, FY1, FY4, and FZ2. 1–2 Sets up – (minus) excitation for shunts FX1, FY1, FY4, and FZ2.
Interfacing with RPC Interfacing with RPC The SWIFT sensor is directly compatible with the MTS Remote Parameter Control (RPC) simulation software. The SWIFT system produces outputs that directly correspond to the uncoupled spindle forces that the MTS Model 329 Road Simulator applies to the vehicle. Traditional instrumentation techniques provide coupled suspension loads data. Using the SWIFT sensor, the RPC simulation software needs to apply less correction to obtain the road simulator drive signals.
Software Utilities Important Contents Introduction This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI software utilities (MTS part number 100214316).
Introduction Introduction The SWIFT utility programs in this distribution are for Win32 Operating Systems (Windows 95, 98, NT, 2000, XP). They are designed to be run from the Command Prompt or MSDOS Shell. However, it is possible to create a shortcut to run the programs. If launched from a shortcut the application window may close immediately when the application terminates making it impossible to see any error messages.
TISTATUS - Low-Profile Transducer Interface Status TISTATUS - Low-Profile Transducer Interface Status This program is used to get status information from the SWIFT Low-Profile Transducer Interface (TI). When the Low-Profile TI has encountered a problem and is blinking an error code, this program can be used to easily interpret the error. For certain errors this program may provide additional information. The program also provides information such as the internal power supply voltages.
TIXFER - Low-Profile Transducer Interface Transfer TIXFER - Low-Profile Transducer Interface Transfer This program is used to change settings within the SWIFT Low Profile Transducer Interface (TI). It can be used to read the current settings and save them to the computer (upload) or write the settings to a Low-Profile TI with values from a file on the computer (download).
TIXFER - Low-Profile Transducer Interface Transfer The following rules apply: Tabs and spaces are allowed. The parameters can occur in any order Names are case insensitive. If a parameter name is not recognized, an error will be reported, and further processing will be stopped. If an error causes the program to abort while downloading, any parameters prior to the error will have been successfully downloaded because parameters are downloaded as they are read.
TIXFER - Low-Profile Transducer Interface Transfer The bridge and angle zero values will change whenever a zero is activated by pressing the Low-Profile TI front panel zero button. Therefore, after a zero is performed the zero values uploaded will not match those downloaded. All parameters within the Low-Profile TI have been calibrated.
TISHUNT - Low-Profile Transducer Interface Shunt TISHUNT - Low-Profile Transducer Interface Shunt This program is a utility with various functions related to shunts. The SWIFT system includes the ability to connect a shunt resistor across each of the resistive bridges in the transducer. This shunt function can be used as a simple verification that the SWIFT system is working normally. Shunt verification activates the shunts and compares the results to those recorded during calibration.
TISHUNT - Low-Profile Transducer Interface Shunt Option 0 Use this option to exit the program. Option 1 Use this option to read the shunt tolerance, the last measured shunt values, the reference values, and the shunt error status. Note The shunt error status is not maintained over power cycles, so it is only valid if the shunt is executed after power is applied. Refer to, “Shunt Error Status,” on page 58 for additional information about shunt error status.
TISHUNT - Low-Profile Transducer Interface Shunt Option 3 Use this option to restore shunt settings from a file. The file format is the same as that used in the tixfer program. Option 4 Use this option to apply a shunt sequentially, reading the eight bridges and six outputs of the Transducer Interface. Note that this option does not update the shunt measured values or error status. A reading is first made with no shunts applied (displayed as the zeroes data).
TISHUNT - Low-Profile Transducer Interface Shunt Option 5 Use this option to command a Shunt Cal in the Transducer Interface. This is the same as pressing the Shunt button on the front panel of the Low-Profile TI. A period is displayed on the screen for every change in the shunt state. This gives you a quick view of the progress.
TISHUNT - Low-Profile Transducer Interface Shunt Setting Up Shunt Calibration Reference Values The tishunt utility provides all of the necessary functions for setting up a Transducer Interface with valid Shunt Cal Reference values. Note This procedure should only be performed by qualified service personnel. Before running the tishunt utility, connect the Transducer cable and Shunt cables from the SWIFT Low-Profile TI to the SWIFT Transducer Assembly.
TISETZERO – Low-Profile Transducer Interface Set TISETZERO – Low-Profile Transducer Interface Set Zero Method This program allows some configuration settings to be changed in a SWIFT Low-Profile Transducer Interface (TI) without modifying a settings file. This program only changes configuration settings, it does not change any calibration settings.
Error Messages Error Messages When a SWIFT utility encounters an error, a traceback message is displayed.
Shunt Error Status Shunt Error Status This is the error status for each bridge from the last shunt cal that was performed. The error status is a bit-mapped status word, where the error is present if the bit is set to 1. Bit 0 = Bridge amplifier was saturated prior to applying the shunt. Bit 1 = Bridge amplifier was saturated after applying the shunt. Bit 2 = Measured delta value failed high. Bit 3 = Measured delta value failed low. Bit 4 = A procedural error occurred (unable to read a value, etc.).
Setting up the Low-Profile Transducer Interface Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI setup (MTS part number 100214316).
Select a Zero Method Select a Zero Method Before you install a transducer and zero it, you must configure the transducer interface (TI) for the appropriate zero method.
Select a Zero Method Calibration File Elements The following figure shows some elements of the calibration file: SWIFT file identifier Description of the file [SWIFT] Name=zero 3 after new tire SerialNum=1234567 Normalization=0 InputSwitches=255 OutputPolarities=40 ZeroAlgorithm=4 AngleMode=0 AngleOffset=82.0898 AngleFixed=0 EncoderSize=0 ZFX1=0.103786 ZFX2=-0.023199 ZFY1=-0.094017 ZFY2=-0.184371 ZFY3=-0.225885 ZFY4=-0.269841 ZFZ1=-0.101343 ZFZ2=-0.045177 KFX1=0.196337 KFX2=0.195604 KFY1=0.169231 KFY2=0.
Select a Zero Method Items you may edit • OutputPolarities–defines the polarities of the six outputs. Change these only if your application requires different polarities from those on the transducer label. • ZeroAlgorithm–selects a zero algorithm for the application. • AngleMode–selects the mode used for determining the encoder sine and cosine. • AngleFixed–used for non-spinning applications. • AngleOffset–used for spinning applications. Normally you do not need to change this value.
Select a Zero Method Zero Algorithm Values Defined (part 2 of 2) Zero Algorithm When to Use Bridge Zero 3 Use this algorithm if you do not need to mechanically level the SWIFT sensor Both the Angle Zero and Bridge Zero buttons are functional. This algorithm will perform both angle zero and bridge zero processes when either of these buttons is pressed. The transducer is unloaded during the zero process.
Upload the Calibration File Upload the Calibration File A unique calibration file was loaded into the TI RAM by MTS before the transducer and transducer interface were shipped. Use the program TIXFER to retrieve the calibration file. TIXFER is a simple DOS-based program that will prompt you for information. 1. Connect a communication cable from the laptop computer or PC to the TI. 2. Insert the SWIFT Transducer Interface Utilities diskette into the laptop computer or PC. 3.

Edit the Calibration File Edit the Calibration File CAUTION Do not change any other items in the calibration file. The calibration file contains offset values for all of the bridge outputs. Changing any of the items other than those listed in the following procedure will cause your calibration file to be incorrect. Take care not to change any values except those listed in the following procedure. If your calibration file is incorrectly changed, reload the original file from the diskette provided by MTS.
Edit the Calibration File 2. If necessary, edit the value for OutputPolarities.
Edit the Calibration File Example Output Polarities Output Polarity Value Description OutputPolarities = 40 Standard Setting from +Fx = fore MTS. Matches the axis orientation on the front +Fy = out from car, left cover of the SWIFT.
Edit the Calibration File C. The AngleOffset value is used when you are operating in encoder mode (spinning applications). This value is summed with the encoder output count, and used to address the sine and cosine RAM when the angle mode is set to 0 (encoder). Negative angles are converted to their positive equivalent so that the readback value range is 0–360°. The AngleOffset value is calculated by the TI during the zero process. At the end of the process it is written to the calibration file.

Installing the Transducer Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the transducer installation with the Mini TI (MTS part number 100214316). The SWIFT sensor can be installed on a vehicle at the test track or on an MTS Series 329 Road Simulator in the test laboratory.
Test Track Vehicle for Slip Ring Sensor Test Track Vehicle for Slip Ring Sensor Equipment required This procedure requires one person.
Test Track Vehicle for Slip Ring Sensor • 12 V power supply (for example, a car battery) Slip Ring Bracket Slip Ring Encoder Hub Adapter Modified Rim Transducer S20-57 Slip Ring Installation Components (Test Track) Importance of bolts Bolts provide exceptional clamp force at the transducer to rim/spindle interface. • Bolts on the inner hub secure the hub adapter to the SWIFT sensor. • Bolts on the outer ring secure the SWIFT sensor to the wheel rim (or road simulator spindle adapter).
Test Track Vehicle for Slip Ring Sensor CAUTION Do not lay the wheel flat while the transducer is attached to it. When the wheel is laid flat with the transducer facing down the weight of the wheel can damage the connectors. Always hold the wheel upright when the transducer is attached to it. If needed, have another person hold the tire upright while you tighten the bolts, or place the wheel on a thin layer of foam to protect the connectors. CAUTION Do not under-torque the lug nuts.

Procedure 1. Remove the current wheel from the test vehicle. 2.
Test Track Vehicle for Slip Ring Sensor 5. Attach the hub adapter to the transducer. Hand tighten the bolts If environmental conditions warrant, coat each fastener with Birchwood Casey Sheath RB1 rust preventative (or equivalent). Lubricate the threads and under the heads of all fasteners, using Molykote g-n paste. A clearance of approximately 0.05 mm (0.002 in) is required between the transducer and the hub adapter.
Test Track Vehicle for Slip Ring Sensor 6. Tighten the mounting bolts. A. Following the sequence shown in the previous figure for the transducer being installed, torque the inner hub bolts in two increments, as shown in the following table. Important Note For the SWIFT 20T, the M8 bolts in the inner bolt pattern (bolts 1–4 in the previous figure) must be torqued, as described, before torquing the M10 bolts (bolts 5–20 in the previous figure).
Test Track Vehicle for Slip Ring Sensor Attaching SWIFT and Wheel Assembly to the Vehicle 1. Before installing the SWIFT and wheel assembly, attach the slip ring antirotate bracket to the vehicle. Since the bracket is unique to each vehicle the slip ring anti-rotate bracket must be provided by the customer. The following are guidelines for manufacturing and locating the bracket. See the next figure.
Test Track Vehicle for Slip Ring Sensor C. Measure, making bends as necessary, and cut the aluminum tube to size. MTS provides an extra long tube with a hinge welded at one end. After fitting the tube to your test vehicle, cut off the excess length. Minimum Clearance Typically approximately 6 mm (0.25 in) depending on tire uniformity. Tire must not hit bracket when loaded or rotating.
Test Track Vehicle for Slip Ring Sensor Installing the Low-Profile Transducer Interface Electronics Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI (MTS part number 100214316). The Transducer Interface (TI) electronics should be securely fastened to the vehicle in a protected location.
Test Track Vehicle for Slip Ring Sensor Note Some data acquisition systems may introduce electrical noise spikes to the battery and cabling. The TI electronics should always be used with the cleanest power supply possible. To reduce the likelihood of noise spikes from the data recorder, we suggest running the power cables in parallel, as shown in the following diagrams. If this does not remove the noise spikes, separate batteries may be required. 3. Ground the TI and data recorder to the vehicle frame.
Test Track Vehicle for Slip Ring Sensor 5. Verify that the shunt contacts are covered. Make sure that the plugs on the slip ring bracket (spider) cover are in place so that no water will enter the contacts. Make sure that the bayonette covers on the shunt connectors are securely locked in place. Each cover should be twisted until it snaps into the retaining groove. 6. Turn on the TI and let it warm up for 15-20 minutes before you zero the strain gage bridges.
Test Track Vehicle for Slip Ring Sensor Setting up the SWIFT Sensor for Data Collection Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI (MTS part number 100214316). To ensure accurate data collection, complete this setup procedure daily before you begin testing.
Test Track Vehicle for Slip Ring Sensor When using one of these zero methods, never rotate the tire directly, or by grabbing the outer diameter of the transducer. This will introduce forces into the transducer bridges that will result in a bad zero process and unreliable data. Choosing a Zero method • Rotate the tire at an even rate to avoid accelerations on the transducer.
Test Track Vehicle for Slip Ring Sensor This zero method samples all eight input bridges on every encoder tick, for one complete revolution. After the data is taken, all eight input channels are analyzed for signal offsets, and the X and Z input channels are analyzed to determine the angular zero point. [SWIFT] Name=zero 3 after new tire SerialNum=1234567 Normalization=0 InputSwitches=255 OutputPolarities=40 ZeroAlgorithm=4 AngleMode=0 AngleOffset=82.0898 AngleFixed=0 EncoderSize=1 ZFX1=0.103786 ZFX2=-0.
Test Track Vehicle for Slip Ring Sensor A. Download the spinning calibration file (xxxxxs.cal) to the computer from the MTS Disk that corresponds to the serial number of the transducer that you are setting up. B. If necessary, modify the zero algorithm and angle mode to fit the application/use requirements as described in, “Edit the Calibration File,” on page 66. C.

Test Track Vehicle for Slip Ring Sensor 4. Run the TISTATUS program to compare the supply voltages to the reference voltages. Type: TIstatus If the supply voltages vary more than 0.5 V from the reference voltages, there is a power supply problem that must be resolved before you can continue. 5. Verify that the calibration file is set up correctly for your testing application. A. Download the spinning calibration file (xxxxxs.
Test Track Vehicle for Slip Ring Sensor Note B. The encoder has a red dot on the mounting flange connected to the slipring bracket and a black dot on the slip-ring connector housing where it interfaces with the mounting flange. These dots, when aligned next to each other, indicate the index mark is under the encoder sensor. Rotate the tire as necessary, until the Fz on the axes icon (see the next figure) printed on the transducer label is pointing up Axes Icon C.
Test Track Vehicle for Slip Ring Sensor 12. Perform, “Verifying the Quality of the Zero Procedure,” on page 95. 13. Look at your data acquisition system to verify that the SWIFT sensor is gathering data. If Zero Algorithm=3 When you zero the TI, you want the vehicle to be fairly level and the transducer to be as close to plumb as practical. 1. Install the SWIFT sensor(s) and data collection equipment on the vehicle. 2. Connect all cables and turn on the power to the TI boxes. 3.
Test Track Vehicle for Slip Ring Sensor 94 Installing the Transducer B. Rotate the tire 1 1/4 to 2 revolutions, until the Bridge Zero indicator starts flashing. Follow the guidelines in, “Considerations for rotating a tire,” on page 85. C. If the Bridge Zero indicator continues to slowly flash after 2 minutes, or if the red Fail indicator flashes, there is an error in the zero process. Run TISTATUS to find out more information. Repeat Steps A and B.
Test Track Vehicle for Slip Ring Sensor Verifying the Quality of the Zero Procedure Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI (MTS part number 100214316). Perform the following consistency checks for each SWIFT sensor while the vehicle (or corner) is elevated. 1. Does Fz measure the approximate weight of the tire/rim assembly? 2.
Test Track Vehicle for Slip Ring Sensor D. Press the Shunt button on the front of the TI box, or use option 5 in the TISHUNT program. The shunt indicator will light continuously for 30–45 seconds. If the indicator continues to flash after shunt calibration is complete, the shunt calibration has failed. Connect to Data Acquisition System Board A Shunt B Shunt A Board B S20-24 Connect the shunt calibration cables 6. Verify that the outputs from the TI box matches those on the calibration report.
Test Track Vehicle for Slip Ring Sensor As the vehicle is set completely on the ground, the output from the SWIFT sensor will read the corner weight of the vehicle from the reference point of the transducer. The output of the SWIFT sensor will be slightly less than the total corner weight of the vehicle, because the SWIFT sensor is inboard of the outer tire and rim assembly, and will therefore not measure the weight of the outer tire and rim assembly.
Test Track Vehicle for Slip Ring Sensor Collecting Data Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI (MTS part number 100214316). After you zero the TI, you are ready to collect data.
Test Track Vehicle for Slip Ring Sensor Important Before beginning data collection, read the cautions on the next page. CAUTION Do not allow the SWIFT assembly to bump into any hard surfaces while you are driving the vehicle. Bumping the SWIFT assembly into hard surfaces such as garage doors, ramps and railings will damage the anti-rotate device, cable, slip ring, slip ring bracket (spider), and transducer. The SWIFT assembly will protrude approximately four inches (102 mm) from the side of the vehicle.
Road Simulator Road Simulator Before you begin Angular correction is required on the test track only. If you are using the same transducer(s) for non-spinning simulation testing you must load the correct software into the TI. The SWIFT sensor must be attached to the test fixture before the vehicle is mounted. Clean all surfaces. It is critical that all surfaces be free of stones, burrs, and grease. CAUTION Do not pressure-wash the transducer or clean it with solvents that would degrade its silastic seal.
Road Simulator Equipment required This procedure requires one person. To install the transducer, you will need the following equipment: • Hub adapter • Modified rim • Spindle housing adapter plate • Connector housing • Locating pins • Small set of hex-head wrenches (both English and metric) • Metric socket head drive set (up to 14 mm) with extension • Molykote g-n paste (MTS part number 011-010-207) • Bolts For SWIFT 20A Transducer 40 size M8 X 1.25 mm 8 size M5 X 0.
Road Simulator Attaching SWIFT Components to the Fixturing Note Install the transducer such that the orientation labeling is consistent with the reference orientation. In most cases, this means installing it so the labels are upright. If an additional angle correction is required after installation, you will need to measure the angle from zero, and then enter a new offset value for the AngleOffset in the TI calibration file (see earlier instructions, “Edit the Calibration File,” on page 66).

Analyzing SWIFT Data Overview This chapter contains examples of data collected from SWIFT installations, and explains how the data can be analyzed.
The Data The Data The following figure shows handling data taken on a flat, winding surface, using a SWIFT sensor and SOMAT software. The driving speed was between 30 and 100 kph (18–62 mph).
Fx Data (Longitudinal Force) Fx Data (Longitudinal Force) Mx+ Direction of Motion nce Dista Fx+ S20-28 This figure shows the Fx (longitudinal force) data. • The offset in Fx after zeroing the SWIFT sensor is due to frictional force and rolling resistance on a flat road. • There is a strong similarity between Fx and Mz, due to the SWIFT sensor measurement characteristics. That is, the SWIFT sensor measures at the transducer centerline.
Fx Data (Longitudinal Force) The following figure illustrates the relationship between Fx and Mz, for this test case, which had a 170 mm (6.
Fz Data (Vertical Force) Fz Data (Vertical Force) The offset force in the Z direction is the combined weight of the car, equipment, and driver at that corner. 5.2 kN = 530 Kg (force) = 1169 lb for this vehicle at static loading.
Mx Data (Overturning Moment) Mx Data (Overturning Moment) Mx ce Y an Dist Distance Z Fz+ S20-29 The moment Mx is the resultant of the forces Fz and Fy, and their respective distances to the center of the SWIFT sensor. After zeroing the SWIFT sensor, with the wheel off the ground, there will always be a small moment Mx present. This is due to the offset of the tire assembly center of gravity from the SWIFT sensor centerline.
Mx Data (Overturning Moment) Channel 4 Mx Data The following figure shows the relationship between Mx, Fz, and Fy, during a cornering event. Fz decreases as the vertical force is shifted to the opposite wheel. Fy, the lateral force, increases to prevent side slip resulting in an increase in the overturning moment, Mx. Mx = Fy x Distance Z +1* Fz x Distance Y Fy Fz Mx After zeroing the SWIFT sensor with the wheel off the ground, a moment Mx will still be present, as the following figure shows. 1.
Mx Data (Overturning Moment) Mx (wheel off ground) = Fz (active weight of the tire and rim outside the transducer) x Distance (CG to SWIFT sensor centerline) Mx offset with the wheel off the ground CG x Fz 118 Analyzing SWIFT Data SWIFT 20 Sensors
My Data (Brake Moment) My Data (Brake Moment) eY anc Dist My My Distance Z Fx S20-30 The moment My should show strong similarities with the force Fx and is calculated by the SWIFT sensor using the distance Z.
Acceleration and Braking Events Example Acceleration and Braking Events Example Shown below is actual road data taken with the MTS SWIFT Sensor, located at the front passenger side of a mid-size passenger vehicle. Data shown is postprocessed to translate the forces and moments from the center of the transducer to the center of the tire.
Acceleration and Braking Events Example Mz: The Mz output noted is corrected to give the aligning moment at the center of the tire. Minimal Mz moments are generated during these straight line acceleration and braking events. Time 6 to 10 seconds: During the relatively steady state acceleration of the vehicle, note the forces recorded. Fz: Approximately 100 lb of the weight of the vehicle can be seen transferring from each front wheel to the rear of the vehicle during steady state acceleration.
Slalom Curve Driving Example Slalom Curve Driving Example Shown below is actual road data taken with the MTS SWIFT Sensor, located at the front passenger side of a mid-size passenger vehicle. Data shown is corrected to translate the forces and moments from the center of the transducer to the center of the tire.
Maintenance Overview This chapter contains scheduling guidelines and detailed instructions for performing preventive maintenance. Preventive maintenance is a set of routine procedures that allow you to extend the operating life of your transducer and the transducer interface electronics. You can prevent excessive wear or possible component failure through regular inspections and simple procedures, such as filter cleaning. The information provided in this chapter is a recommendation only.
Transducer The transducer requires a minimum amount of maintenance. CAUTION Do not pressure-wash the transducer or clean it with solvents that would degrade its silastic seal. Pressure-washing the transducer or cleaning it with certain solvents can damage it or degrade its silastic seal. Avoid pressure-washing the transducer. Use only solvents that will not degrade the silastic seal. CAUTION Do not use high-pressure-air to clean debris from around the transducer connectors.
Low-Profile Transducer Interface Important This section includes information related to the Low-Profile Transducer Interface (TI). For SWIFT transducers designed to operate with the newer Mini TI, there is a separate manual that documents the Mini TI software utilities (MTS part number 100214316). The electronics for your transducer require a minimum amount of maintenance. Ensure that they remain in good condition by checking the ventilation and cleaning the fan filter at regular intervals.
Cables Monthly Inspect all electrical cables monthly, or after every 160 hours of operation. Always turn off the electrical power before you disconnect, repair, or replace a cable. 1. Check the condition of the cables for cuts, exposed wires, or other types of damage, loose connectors, and cracked or worn cable covers. Tighten any loose connectors. Replace any cracked or worn cables. 2. Ensure that cable connectors are securely plugged into their respective receptacles. 3.
Troubleshooting This chapter covers basic set-up related troubleshooting tips. Please read this chapter to investigate problems that you observe. In many cases, these problems will be set-up related and can be corrected as described in this section. In the event that these troubleshooting tips indicate that there is a component failure, or the correction tips do not correct the problem, contact MTS.
Troubleshooting Guide (part 2 of 14) Symptom Possible Causes Solution The battery or power supply wiring is reversed. If using a car battery, check that the wiring is correct. If the wiring has been reversed and the power switch was turned on, it is likely the fuse has blown. The main fuse has blown. The 3A fast-blow fuse (F3) is located on the rear of the Induction Power Source.
Troubleshooting Guide (part 3 of 14) Symptom Possible Causes Solution Some or all transducer output signals read 0 volts at the TI output even when a load is present. The TI is not turned on. Check that TI is turned on and the green power indicator is lit. The transducer signal cable is not connected. Check that the cable is connected between the back of the TI box and the slip ring or the connector housing (for a road simulator). Output cables are not connected.
Troubleshooting Guide (part 4 of 14) Symptom Possible Causes Solution The tire rotation was not continuous or smooth. The tire should be rotated at a slow and constant velocity. Changes in acceleration or jerkiness can produce inertial loads which will affect bridge zeroes. If the tire is rotated in one direction for part of the time, any small rotation in the other direction will cause bridge zero and angle errors in the spinning zero mode.
Troubleshooting Guide (part 5 of 14) Symptom Possible Causes Solution The reference angle of the transducer is set incorrectly in non-spinning mode. The AngleFixed value in the TI calibration file is initially set to zero, indicating that the coordinate outputs on the transducer’s label are correct when the label is upright. If the label is not upright, or if the AngleFixed value in the calibration file is not set correctly, the angular transformation may be causing the error.
Troubleshooting Guide (part 6 of 14) Symptom Possible Causes Solution Excessive noise during the zero procedure caused an incorrect bridge zero, or the angle computation to be calculated incorrectly. Electrical Noise: The SWIFT sensor has power conditioning, shielded cables and on-board amplification to reduce electrical noise. However, if the TI or transducer are very near a powerful noise source, some noise can be picked up with the signal.
Troubleshooting Guide (part 7 of 14) Symptom Possible Causes Solution The data acquisition scales are set incorrectly. Check that the data acquisition scales are set correctly. The full scale calibration range is shown on the Calibration Report, with 10 V = Full Scale (unless you requested custom calibration output before calibration at MTS).
Troubleshooting Guide (part 8 of 14) Symptom Possible Causes Solution Shunt Calibration indicator light blinks after shunt calibration indicating Shunt Calibration failed. The shunt cables are not connected, or are damaged, or their connectors are not secured. Check that the shunt connectors were securely installed during the shunt calibration procedure. Verify that the cables are not nicked, cut, or damaged, and that no connector pins are damaged.
Troubleshooting Guide (part 9 of 14) Symptom Possible Causes Solution Shunt Calibration indicator light blinks after shunt calibration indicating Shunt Calibration failed (continued). The shunt reference values were changed. Use the TIXFER utility to upload the current calibration file. Check the file to verify that the variables ShuntDeltaRef are the same as shown on the original calibration file provided by MTS. The eight ShuntDeltaMeas values should read approximately the same for all eight bridges.
Troubleshooting Guide (part 10 of 14) Symptom The output signal polarity is incorrect Possible Causes Solution The gains have been changed in the calibration file. As the bridges are shunted, the eight raw bridge outputs pass through the TI box and have the calibration gains applied to them. If the calibration file has been changed or modified, the six bridge 10 V outputs will reflect this.
Troubleshooting Guide (part 11 of 14) Symptom Possible Causes Solution Spinning Application: Vehicle Coordinate System Outputs have unusual or incorrect waveform shapes to them. (Angular output may need to also be recorded to troubleshoot based on per-revolution outputs) A one-time-per-revolution of tire signal appears while the vehicle is driving straight on a flat surface. The mean level on FX and FZ is equal to zero, and the amplitude is fairly consistent during straight driving on a flat surface.
Troubleshooting Guide (part 12 of 14) Symptom Possible Causes Solution Spinning Application: Vehicle Coordinate System Outputs have unusual or incorrect waveform shapes to them. A two-time-per-revolution of tire signal is showing up when the vehicle is driving straight on a flat surface. Gain settings: Verify that the TI electronics calibration file gain settings have not been modified.
Troubleshooting Guide (part 13 of 14) Symptom Possible Causes Solution Spinning Application: Vehicle Coordinate System Outputs have unusual or incorrect waveform shapes to them (continued). A two-time-per-revolution of tire signal is showing up when the vehicle is driving straight on a flat surface. Gain settings: Verify that the TI electronics calibration file gain settings have not been modified.
Troubleshooting Guide (part 14 of 14) Symptom Possible Causes Solution Spinning Application: Vehicle Coordinate System Outputs have unusual or incorrect waveform shapes to them. (Continued) A four-time-per-revolution of tire signal is showing up when the vehicle is driving straight on a flat surface. Wheel force transducers often have a modulation error with a cyclic frequency equal to the number of beams on the transducer.
