Take vehicle running through a long-span cable-stayed bridge as an example to study the vibration rule of vehicle and bridge in the process of vehicles running on the large span bridge. Vehicle-bridge coupling numerical analysis model is established to study the changing rule of vertical displacement of the vehicle, vehicle wheel vertical contact force, the vertical displacement of the bridge and the impact coefficients of bridge while different quality of vehicles running on the bridge. The results show that, the heavier the vehicle, the greater and the more obvious wave of the vertical displacement change of bridge main-span across. The heavier the vehicles, the more obvious the change of the vertical displacement and torsion angle of cable-stayed bridge main-span across.
