摘要：

With a vertical metro vehicle model including the flexibility of car body, the influences of car body stiffness and the coupled vibration between the metro vehicle flexible car body and bogie bounce mode are researched. Results show that the higher the car body stiffness is, the lower the influences of car body flexibility would be on the ride quality and it is the geometric filtering phenomenon rather than the bogie natural frequency of bounce mode that causes the car body resonant vibration. An example study shows that when the first bending frequency of the fully equipped metro vehicle coincides with that of bogie bounce mode, there will not have the resonant vibration of the flexible car body.
