Hi,I use accelerator(EVAL-ADXL335Z) to measure acceleration of the actuator in the moment of turning back.
The structure of the experiment is in the following picture.
Then I use Labview software to control the actuator's movement.The actuator moves at the constant speed and turns back in the terminal.The moving amplitude of the actuator is 40mm.
The waveform of Z-axis output is captured by oscilloscope's probe.
The waveform is in the following picture.
I think the waveform represents the displacement not acceleration of turning back.
I don't know which part is wrong in the measurement.
Please give advice to help me.
