A correction technique on dynamic characteristics of a pressure bar test system based on dynamic calibration data

A shock-tube calibration platform was established to solve the insufficient dynamic response of a pressure bar test system in the shock wave measurement for chemical explosive experiments.The dynamic characteristics of the pressure bar test system was investigated by adopting the following methods such as system identification,dynamic compensation and the combination of time domain analysis and frequency domain estimation.A new-type dynamic compensation filter was designed to improve the dynamic characteristics of the test system.And the compensation effect was tested.The results show that the frequency bandwidth of the test system is expanded and the response time is reduced.
