摘要
Abstract
In the present work,to obtain the accurate measuring curve of explosive shockwave reflected pressure,we analyzed the three factors that influence the peak value,i.e.the band width of the pressure test system,the pressure test method,and the length of the signal transfer wire,adjusted the dynamic calibration on the shockwave pressure measuring system using the shock tube,and obtained the dynamic characteristics of the system using the ideal method of differential.With the improved version of the levy method,the parameter model about the dynamic characteristics was built.The Butterworth filter was designed as the system after the compensation for the calculation of the dynamic compensation tache.This method can expand the work frequency segment of the pressure test system and reduce the amplitude of the inherent frequency point so that the shock wave reflected pressure curve was rectified.It was found that this rectification and compensation method can correct the peak value of the shockwave reflected pressure and reduce the error from the dynamic characteristics of the shockwave pressure measuring system.This study can significantly raise the peak value accuracy of the shockwave reflected pressure and provide technical support for weapon damage assessment.关键词
