摘　　要：研究在轴重相同条件下,车辆相关结构参数及悬挂参数变化对独立轮对型式轻轨车辆系统动力学性能的影响特性,特别是研究通过曲线时的轮轨作用力、脱轨系数、摩擦功率的变化情况以及在轨道随机不平顺激扰作用下车辆乘坐舒适度指标变化特性。The influence of structural and suspending parameters,such as axle distance,primary stiffness,wheel/rail gauge and so on,to the dynamics of light rail vehicle system with in depen dently rotating wheel is offered.And great attention is paid to the system dynamic index such as wheel-rail forces,derail coefficient ,friction power when the ve-hi cle negotiating curve and the ride index while running on the straight line with stochastic excitation in this paper.
