摘　　要：将列车空气动力学和多体动力学理论相结合,利用SIMPACK软件建立国内某时速400 km中国标准化动车组的动力学模型。介绍考虑侧风作用下的车辆动力学仿真计算方法,通过此方法较为全面地研究在“中国帽”侧风风载下,不同风速和车速下的列车运行安全性问题,为特殊风环境下高速动车组的安全运行速度提供理论依据。研究表明:侧风风速越高,列车受到的气动载荷越大,列车的最高安全运行速度越低,因此在车辆通过强风区时,需要采取限速、停运等安全措施。By combining train aerodynamics with multi-body dynamics theory and applying SIMPACK software,designes a dynamics model of a domestic OEM of 400 km/h Chinese standardized rolling stock.The simulation method of vehicle dynamics under the consideration of side wind is introduced,by which the safety of train operation under different wind speeds and vehicle speeds is studied more comprehensively under the"Chinese cap"side wind load,which provides a theoretical basis for determining the safe operation speed of high-speed rolling stock in special wind environment.The study shows that the higher the side wind speed,the greater the aerodynamic load on the train,and the lower the maximum safe operating speed of the train.Therefore,it is of necessity to take safety measures such as speed limit and stopping when the vehicle passes through the strong wind area.
