Mechanical testing device |
摘要 |
A mechanical testing device has a rigid frame and a piezo translator connected to the frame. A Wheatstone bridge is connected to the translator to produce an electrical signal related to the compression of the translator, wherein a sample positioned between the piezo translator and the frame is subjected to loads by the movement of the translator. A sensor detects the force applied to the sample by the piezo translator, and produces a signal indicative of the force. A computer receives the Wheatstone bridge electrical signal and the signal indicative of the force applied to the sample. The computer controls the advancement of the translator to allow the application of precise amounts of compression to the sample.
