摘要
为了满足整车道路模拟试验对载荷谱的需求,本文介绍实车动态载荷谱采集、处理、分析和特征提取的方法,为进行实验室整车道路模拟试验以及CAE仿真分析奠定基础。
In order to meet the requirements of the vehicle road simulation test to the load spectrum,the paper introduces the methods of collecting,processing,analyzing and feature extracting for the real vehicle dynamic load spectrum so as to lay a foundation for the lab bench simulation test of the vehicle road and the CAE simulation analysis.
