冲击波压力传感器组件动态特性补偿研究
Dynamic Characteristics Compensation of the Blast Wave Pressure Sensor Assembly
摘要
Abstract
To suppress the parasitic effect of the explosion field,corresponding suppression measures should be taken for the blast wave pressure sensor,which narrows the working frequency band of the sensor assembly and leads to measurement distortion.In order to realize engineering distortion-free measurement,it is necessary to dynamically compensate the sensor assembly.Firstly,the typical shock wave pressure sensor assembly is dy-namically calibrated,and the non-parametric model of the dynamic characteristics is obtained by the differential method.Then the dynamic characteristic parameter model is identified.Furthermore,the dynamic compensation digital filter is designed to implement the 0～40 kHz dynamic compensation for the typical sensor assembly.And the scientificity and effectiveness of the compensation are verified.Finally,the typical blast wave pressure signal is dynamically compensated.The study is of great significance to improve the measurement accuracy of blast wave pressure and accurately evaluate the damage power.关键词
