摘　　要：介绍了变轨距转向架动车组车辆的结构特点,运用动力学仿真软件SIMPACK,在考虑轮轴间隙的情况下,建立了变轨距转向架车辆系统非线性模型,分析了车辆在1435 mm轨距、1520 mm轨距线路上运行时的动力学性能,包括运动稳定性、运行平稳性和运行安全性等,并预测了车辆在车轮磨耗状态下的动力学性能。结果表明,变轨距转向架动车组车辆的动力学性能满足相关标准要求,运动稳定性、运行平稳性和运行安全性有一定的裕量。This paper introduces the structural characteristics of the gauge-changing bogie multiple units,uses the dynamic simulation software SIMPACK,and establishes a nonlinear model of the gauge-changing bogie vehicle system considering the wheel axle clearance,analyzes the dynamic performance of the vehicle when it runs on the 1435 mm gauge and 1520 mm gauge lines,including stability,ride comfort and safety,and the dynamic performance of the vehicle under wheel wear is predicted.The results show that the dynamic performance of the gauge-changing bogie vehicle meets the requirements of relevant standards,and there is a certain margin for stability,ride comfort and safety.
