Research on dynamic performance of virtual rail vehicle dynamics under different levels of cross wind
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.
