| Abstract: | Based on parameter transmission,solution to control and dynamic mesh techniques,the cross wind fluid dynamics model and the multi-body system dynamics model of high-speed train were established.By collaboratively simulating the external flow field and system response of train,the stable attitudes and aerodynamic loads under different cross wind environments were obtained.The running safety indexes were studied,the critical speeds of running safety under different cross wind environments were analyzed,and th... |
