Abstract
In order to solve the problem that the track structure is oversimplified in the dynamics study of heavy haul railway, a wagon vehicle-track coupled dynamic model is proposed in this paper. The track structure is more detailed and is modelled by a composite double-layer dynamic model. The upper layer is composed of two rails and the lower layer is composed of many sleepers. The rails are connected with sleepers by the rail pads. This more detailed model is then used to study the influences of the stiffness of the rail pads on the system dynamic performances of heavy haul railway. The results reveal that the proposed model is more practical to study the dynamic problems of heavy haul railway, and the model is able to subtly analyze the dynamic influences of local structure on the wagon vehicle-track coupled dynamic system. The results also shows that the stiffness of the rail pads has a great impact on the vertical wheel/rail force, the dynamic responses of the wagon and the vertical displacement of the rail. The smaller stiffness of the rail pads will worsen the wear process of the rail and aggravate the vibration displacement amplitude of the fasteners by increasing the vibration of the rail. Therefore, an appropriate stiffness of the rail pads is of great significance to extend the service life of the track and to reduce the maintenance and operation cost.
