摘　　要：作者提出的符号矩阵运算方法和用C语言编写的WSEM程序用于机车车辆动力学的研究中,可导出机车车辆在惯性坐标系中的线性和非线性符号式方程。通过计算实例表明,符号式方程的构造方法比数字式先进,而且运算时间短并准确。该程序具有通用性,除用于机车车辆系统外,还可用于其他机械系统。This paper presents a computerized matrix methed and a progam named WSEM written in Clanguage,which derives the symbolic linear and nonlinear equations of motion of rail vehicles inan inertial frame, Examples presented shows this method and the program to be very effective interms of computation time as well as accuracy. The software mentioned above can also be used formechanical systems other than rail vehicles.
