Functional Description Introduction This section contains the functional description of the MTS Series 201 Hydraulic Actuator and a description of the actuator components. It also contains the actuator specifications such as model numbers, force ratings, dimensions,and weights. Functional Description The Series 201 Hydraulic Actuators are heavy duty, fatigue-rated force generation components.
Functional Description If the piston rod contacts some external reaction point, then a force is applied to that point equal to the effective piston area times the actuating pressure. The main criteria for selecting an actuator are the force and stroke (displacement) required for the job. What you need to know MTS Systems Corporation assumes that you know how to use your controller. See the appropriate manual for information about performing any controllerrelated step in this manual’s procedure.

Installing the Actuator Installation Installing the Actuator Whenever lifting the actuator, always use four lifting shackles, installed securely into the lifting holes in the front and rear end caps. Fixtures can be mounted to the actuator piston rod and rear end cap. The piston rod is threaded to accept a stud. The rear end cap has between four and sixteen threaded holes for the mounting of a swivel.

Installing Accessories with Spiral Washers Swivel Head Spiral Washers Connector Studs Spiral Washers Actuator Rod Compliant Material Load Cell Compliant Material Upper End Cap Installing Accessories with Spiral Washers The procedure requires two spanner wrenches and assumes that you are familiar with all operating aspects of your system. 1. Ensure that system hydraulic pressure has been reduced to zero before proceeding.
Installing Accessories with Spiral Washers Connector Stud Medium Thickness Spiral Washer Rotation to Increase Thickness Connector Stud Do Not Exceed 6. Place the spiral washers together with the spiral surfaces facing each other. 7. Place the set of spiral washers over the connector stud and rotate them until they are at minimum thickness. Place the appropriate accessory (load cell, fixture, for example) on the connector stud and tighten the spiral washers by hand. 8.
Removing Accessories with Spiral Washers WARNING Do not exceed the maximum HPU output pressure or apply a force greater than any force train component capacity. Exceeding the tensile load capacity of any element in the force train can cause equipment damage and/or personal injury. It is necessary to temporarily exceed the tensile load capacity to achieve the requirements of Step 12 in this procedure. This is accomplished by increasing the output pressure of the HPU.
Removing Accessories with Spiral Washers 2. Install the actuator in a suitable fixture that can withstand a tensile load 10% to 20% greater than the maximum load to be applied during testing. 3. Select force control at the system controller. 4. Apply system hydraulic pressure according to applicable system procedures. WARNING Do not exceed the maximum HPU output pressure or apply a force greater than any force train component capacity.
Series 201 Actuator Operation Operation This section discusses the operation of the Series 201 Hydraulic Actuator and the optional displacement transducer. Series 201 Actuator Operation Actuator piston rod movement is accomplished by supplying high-pressure (21MPa [3000 psi] maximum) hydraulic fluid to one side of the actuator piston and opening the other side to a return line. The pressure differential across the piston forces the piston rod to move.
Optional Displacement Transducer Operation LVDT The LVDT is an electromechanical device that provides an output voltage that is proportional to the displacement of a moveable core extension. The core extension is attached to a core mount that is secured inside the piston. The core extension is axially oriented in the LVDT coil. The LVDT coil is connected to an LVDT mounting that secures the LVDT assembly.
Maintenance Series 201 Hydraulic Actuators are designed for extended periods of operation with minimal maintenance requirements. A summary of the routine maintenance procedures is listed below. As necessary If a compression relief valve is installed, check and adjust the compression relief valve operating pressure to ensure that the maximum actuator compression force is consistent with the current test requirements. Check the torque of bolted connections to ensure system integrity.
