摘　　要：介绍了城轨列车铰接式转向架基本结构组成,建立了5联单元车组的动力学模型,利用SIMPACK多体动力学仿真软件对单元车组进行了运行安全性、稳定性、平稳性和曲线通过性能分析。仿真分析结果表明,城轨列车铰接式转向架具有良好的动力学性能,能满足城市轨道交通车辆的运行要求。The basic structure of articulated bogie was introduced and a model of five - vehicle group was established. Then the dynamic performances of the vehicle group which includes stability, ride quality and curving behavior were calculated by the multi - body dynamic analysis software SIMPACK. The numerical results indicated that the bogie of vehicle group possesses good dynamic performance which can meet the demand of the application of urban rail.
