On the basis of collecting and arranging datum on coupling vibration of vehicle and bridge, in this paper the motional equations set of vehicle-bridge coupling vibration under the autologous assumption are deduced. What's more making use of Vc++, a professional procedure (CQZD) is programmed which can analyse the vehicle-bridge coupling vibration. Representing the definition of impact coefficient, taking the Bu-Liu River Bridge in GuangXi as subjects, analyses the influencing factor of bridge impact coefficient from vehicle, it...
