摘要
为了研究虚拟轨道车辆在不同级别横风下的动力学性能,基于非线性胎地耦合关系建立了3编组虚拟轨道车辆多体动力学模型,研究虚拟轨道车辆在AW0和AW3状态下,不同级别横风对其胎地垂向力、抗倾覆稳定性、抗侧滚性能等主要动力学指标的影响。结果表明:AW0状态且低速工况下,不同风级的风载和运行速度对各编组车辆影响较小,车辆动力学性能等指标基本一致;AW3状态下,各个指标值均随着运行速度和风级的提高而增大,且AW0状态下车辆的抗倾覆稳定性总体上优于AW3状态;针对各编组车辆而言,中间车的抗侧滚性能优于头车和尾车,其中尾车的抗侧滚性能最差,但各编组之间的抗倾覆稳定性相差不大。
In order to study the dynamic performance of virtual rail vehicles in different levels of cross⁃wind,a multi-body dynamic model of a 3-car virtual rail vehicle is established based on the nonlinear tire ground coupling relationship.The influence of different levels of crosswind on the vertical force of tire ground,anti-overturning stability,anti-rolling performance and other main dynamic indexes of vir⁃tual rail vehicles under AW0 and AW3 conditions is studied.The results show that under AW0 state and low speed condition,wind level has little influence on each marshalling vehicle,and Vehicle dy⁃namics performance and other indicators are basically the same.In the AW3 state,each indicator value increases with an increase of operating speed and wind level,and the overall anti overturning stability of the vehicle in the AW0 state is better than that in the AW3 state.For each group of vehicles,the anti-roll performance of the middle car is better than that of the front and rear cars,with the rear car having the worst anti roll performance,but the anti-overturning stability between each group is not sig⁃nificantly different.
