【摘要】 在复模态分析与演变谱分析的基础上，对变速行驶车辆由路面激发的演变随机响应问题给出了一般解法，并以二轴汽车简化模型为例进行了说明更多还原

【Abstract】 Based on the complex modal analysis and the evolutionary spectrum,a general method for obtaining the road induced evolutionary random response of a vehicle travelling with variable speed is suggested in this paper.As an illustrative example,the road induced random response of a half car model is explored in detail.更多还原
