摘要
利用有限元法,建立了车辆-轨道耦合系统竖向振动分析模型。利用该模型对列车经过错牙和路桥过渡段时轨道结构的动力响应进行了分析,计算结果为既有线提速和新线建设提供设计依据。
Vertical vibration analysis model for vehicle/track coupling system is developed by means of finite element method. Using this model, dynamic responses of track structure when train passing through rail joints and transitions are investigated. The computational results provide the theoretical basis for raising speed on the existing lines and designing the new railway.
