随机路面行驶车辆振动响应的快速虚拟激励算法

本文推广了文献（１），文献（２）中针对单一随机过程激励问题提出的平稳随机振动响应的快速虚拟激励算法，使其适用于多过程联合输入的行驶车辆随机振动情况。这种算法的特点是计算形式简单，效率高，可算出理论上的精确解和计及路面不平度与行驶车辆激励之间存在的相位差和相干性。

A Fast Computing Method for Random Vibrations of Road Vehicles

Based on the relevant papers, a fast excitation computation metood is proposed in this paper for stationary random vibration analysis with multi-process input based on the corresponding algorithm for single random process. This method is simple efficient and its accuracy is equivalent to that of conventional matrix transfer method. In addition, phase differences and correlations among wheels can be easily evaluated.
