| Abstract: | 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 characteris... |
