研究了列车动力学计算模型的建立方法 ,给出了列车系统状态矩阵的构成及其计算方法 ,采用SIMULINK仿真工具 ,建立了多车编组的垂向和横向列车模型。分别对列车的垂向和横向列车动力学进行了实例计算 ,说明了在高速动车组中采用列车计算模型分析各车辆间悬挂作用的必要性和有效性。
Abstract:The modeling method for train dynamics has been investigated both on frequency domain and time domain. A method of construction of state-space matrix of train dynamics is given. For time domain simulation,two examples for vertical and lateral train dynamics are illustrated with some results,which reveal the performance improvement of train on vibration with inter-vehicle suspensions.
