摘　　要：市域列车不停车高速穿越地下站时引起的气动效应将影响行车安全。利用SIMPACK动力学软件进行列车动力学性能仿真,分析市域动车组经过车站变截面区域时的动力学响应,探讨突变气动载荷作用下列车运行安全性及平稳性,研究市域动车组越行典型地下岛式车站时的车体动态偏移量的影响规律。结果显示,在通过截面积发生突变的区域时,车体将产生较大偏移晃动,特别是在尾车驶离中隔墙时,横向动态位移最大达到36.93mm;车速由120km/h增加至200km/h时,最大横向动态偏移量增长224.52%。Suburban trains crossing underground stations can effectively improve the transportation efficiency,but also bring significant aerodynamic effects.SIMPACK dynamics software is used to simulate the dynamic performance of the train,analyze the dynamic response of the Suburban train set when it passes through the area of variable cross-section of the station,explore the safety and smoothness of the train operation under the action of the sudden change of aerodynamic load,and study the influence law of the dynamic displacement of the car body of the city train set when passing through a typical underground island station.The results show that when passing through the area with a sudden change of cross-sectional area,the car body will generate a large offset,especially when the tail car leaves the center partition wall,the maximum lateral dynamic displacement reaches 36.93 mm.The maximum lateral dynamic offsets of the tail vehicle increased by 224.52%when the vehicle speed was increased from 120km/h to 200km/h.
