摘要
在复模态分析与演变谱分析的基础上，提出了时不变线性系统在一般演变随机激励下的时变均方响应的一个简便实用解法。并以简化模型为例，用本方法考察了变速车辆的路面响应问题。
Based on the complex modal analysis and the evolutionary spectrum analysis, a practical method for finding the time dependent m.s. response of a time invariant linear system subjected to common source evolutionary random excitations is suggested in this paper. As an example, through a simplified model the ground induced nonstationary random response of a vehicle travelling with varying speed is obtained by the method.
