铁路高速化使得车辆在行驶过程中受到的气动冲击加剧,严重影响车辆的乘坐舒适性。为了改善高速列车乘坐的舒适性,研究了高速列车会车横向冲击的半主动控制方法。建立车辆系统动力学模型,分析会车振动的传递特性和天棚阻尼控制方法的局限性,针对会车横向振动特性提出会车横向冲击半主动控制方法,对车辆气动冲击进行控制。利用计算机仿真方法验证会车控制的效果。结果显示,控制后由会车气动冲击引起的车辆横向振动平均减幅达到35%～45%。
High-speed railway makes the vehicle in the course of the impact of the aerodynamic impact, seriously affecting the ride comfort of the vehicle. In order to improve the comfort of high-speed trains, the semi-active control method of transverse impact of high-speed trains will be studied. The dynamic model of vehicle system is established. The transmission characteristics of vehicle vibration and the limitations of ceiling damping control method are analyzed. According to the lateral vibration characteristics of the vehicle, a semi-active control method of transverse impact of the vehicle is proposed to control the aerodynamic impact. Using computer simulation method to verify the effect of vehicle control. The results show that the average reduction of lateral vibration caused by the aerodynamic impact of the car will be 35% ~ 45%.
