摘　　要：为了研究高速列车在横风作用下的运行安全性,建立了定常稳态风载荷模型,提出定常稳态风载荷的计算方法,并对共计20种工况下的横向力,倾覆力矩和摇头力矩进行了计算.基于多体动力学基本理论和多体动力学软件SIMPACK,完成了某型号高速列车仿真模型的建立以及广义力载荷的加载,完成车辆的动力学仿真,绘制出不同安全性指标仿真结果图像,并对车辆的运行安全性进行分析和评价,提出改善车辆运行安全性的方法.In order to study the operation safety of high-speed train under crosswind ,a steady-state wind load model was established ,and the calculation method of steady-state wind load is proposed. The transverse force and the overturning moment were obtained under a total of 20 working conditions. The shaking head torque was calculated. Based on the basic theory of multi-body dynamics and multi-body dynamics software SIMPACK,he establishment of a high-speed train simulation model and the loading of generalized force loads were completed. The vehicle safety indexes such as derailment coefficient , overturning coefficient ,wheel load shedding rate,wheel and rail vertical force,and axle lateral force were obtained. The vehicle dynamics simulation was completed ,and the simulation results of different safety indicators were drawn ,and the vehicle's operational safety was analyzed and evaluated. The methods for improving the operational safety of vehicles are proposed.
