THE STATE OF ART OF STUDY ON VEHICLE-BRIDGE COUPLING VIBRATION

The studies about vehicle-bridge coupling vibration have been summarized, especially those in the last 20 years. Some results and conclusions were obtained in the following four aspects: vehicle-bridge modeling, wheel-rail contact relationship, numerical calculations and engineering applications. It is an inevitable trend to establish more refined and efficient vehicle-bridge coupling vibration model, to incorporate more factors as a whole, and to analyze comprehensively the interaction effects of vehicle and bridge.
