A piezoelectric test device is researched and fabricated

aiming at the problem of dynamic force measurement of circumferential power system. On the one hand

the first-order natural frequency of the test system is not less than 200 Hz can be obtained through the modal analysis

hammering method and motion mechanism analysis. On the other hand

through static performance calibration

some static performance indicators such as nonlinear error which is less than 1. 08 %

repeatability which is less than 1. 25 %

and interphase interference which is less than 3 % are obtained. The main performance indexes of piezoelectric test device meet the requirements of test precision.
