应用冲击响应谱分析汽车被动安全性试验中的冲击信号

Analysis of shock Signal in Testing of Motor Vehicle Passive Safety by Applying Shock Response Spectrum

冲击响应谱，一般可定义为单自由度系统对于不同阻尼系数及固有频率的峰值响应。本文应用冲击响应谱的方法，对汽车被动安全性试验研究的冲击信号进行了分析，并对联合国欧洲经济委员会（ECE）法规进行了探讨和研究。还提出了一种从响应域研究冲击信号的方法。

簊hock response sprectrum may be defined generally to be peak response of a system of single freedom degree to various damping coefficient and inherent freguency. This article carries out analysis of shock signal in motor vehicle passive safety experimental study by applying the method of shock response spectrum. It studies regulations of the Economic Committee of Europe (ECE)and brings up also a researching method of shock signal from response domain.
