Dynamic calibration method and system of ultra-high g accelerometer and piezoelectric force transducer

A dynamic calibration method and system of ultra-high g accelerometer and force transducer are presented in this paper. The most important feature is the method of obtaining shock acceleration of 100000 g and more. The dynamic excitation signal generator (shock acceleration/force generator) and recording and signal processing circuit diagram are presented at the first part and then more than 20 times calibration results of acceleration amplitude are given. The experimental shock responses of both an accelerometer and piezoelectric force transducer, the dynamic mathematical models (including difference equation, transfer function and frequency responses) and dynamic performance of the piezoelectric force transducer are given in the last part.
