| Abstract: | On the basis of the theory of continuous elastic discrete point supporting beam, the transient dynamic finite element method is used to study transient dynamic response of the track system with the change of the train speed, the vehicle load, the vehicle stiffness and the foundation stiffness. The results indicate that the exciting frequency of the train and track system frequency determine vibration level of the track system. |
