| Abstract: | Based on wheel/rail interactions, a coupling dynamics model of high-speed train, slab track and bridge is established. Using the general simulation program TTBSIM for dynamics simulation of train, track and bridge, the dynamical performances of train, slab track and bridge are analyzed when the high-speed train passes through the bridge with different speed. The results show that the slab track on bridge can assure the safety of train operation, ride comfort and the safety of bridge structure. |
