In order to research the influence of the flexible car body on the vehicle system dynamic performance and to achieve the reasonable match between high speed and lightweight，it is necessary to build vehicle system dynamic model with the rigid car body replaced by the flexible car body. Due to the lower structure natural vibration frequency of car body, the influence of carbody flexibility on vehicle system dynamic performance is more influential. The influences of structural vibration of car body on vehicle system dynamics performance were studied by finite element analysis (FEA) method and multi-body system (MBS) dynamics theory. Rigid-flexible coupled vehicle system dynamic models were built up and the car body key location’s vibration was analyzed through vibration transmission chain. The results show that the influences of high speed carbody structure vibration on vehicle system dynamics performance are distinguished especially in the domain of car body natural vibration frequency.
