提取电子设备冲击响应时域特征参数的方法

A Way to Extract the Features From the Time History Response of Electronic Equipments Under Shock Load

针对如何从电子设备冲击响应时间历程中提取时域特征参数的问题,以典型冲击响应时域实测数据为研究对象,将冲击实测数据划分为冲击前、冲击中和冲击后3个分段,明确了冲击响应时域特征参数冲击峰值Ap和冲击持续时间Te的定义,提出了一种提取电子设备冲击响应时域特征参数的方法并编制了计算机程序。对数据实例的处理结果表明该方法是正确、可信的。

Aiming at the problem that how to extract time domain features from the time history response of electronic equipments under Shock Load,some typical time history data acquired from shock tests was studied.Then shock test data can be divided into three segments,such as the front segment the middle segment and the back segment.Also two time domain features were difined:the shock peak,Ap,and the shock duration,Te.Subsequently a way to extract the features from the time history response of electronic equipments under shock load was peoposed,at the same time a computer programe was developed as a software tool.Finally the tool was uesed to peocess some shock test data,some beautiful results was obtained,therefore the validity and credibility of the method was verified.
