摘要
本文讨论了五自由度汽车模型对非平稳随机激励的响应。为了对汽车非平稳随机振动进行演变谱分析,本文采用“协方差等效”建模,把“调频结构”的非平衡过程变换成为“调幅结构”的平稳随机过程。
The nonstationary response of a 5-DOF Vehicle is analysed in thispaper. For the purpose of applying the evalutionary spectral analysis tononstationary random vibration of vehicle, this paper transforms the non-stationary process having a 'frequency modulated' structure into a station-ary process having an 'amplitude modulated' structure by using the 'co-variance equivalent' modelling.
