Determine the Vibration Amplitude, Velocity, and Acceleration
Figure 2 shows the plot for the strain measured from one of the beams during free
vibration.
Figure 12 Strain Measured from Vibrating Beam
The vibration amplitude, or maximum displacement at each peak, is derived from the
peak strain in the first vibration cycle and the beam dimensions with the relationship below.
The maximum velocity and acceleration is derived with the maximum displacement and
acceleration, as shown in Table 6.
