Dynamic Simulation of Vehicle Floating Bridge System Based on ADAMS

Mathematic model of floating bridge elastic base infinite beam is established. The vehicle is simplified as moving mass and moving vibration mass respectively, and dynamic responses of floating bridge under the action of vehicle are studied. The three-dimensional vehicle -floating bridge model is established in the ADAMSNiew. By using of its powerful solver, the dynamic responses of continuous hinged floating bridge under the action of the two vehicle models are studied. The results show that the vibration characteristics of vehicle have a great influence on the hinged force, the hinged force when considering the vehicle as moving vibration mass account for 62.75% of the hinged force when considering the vehicle as moving mass. The contact forces between the vehicles and the floating bridge also have great differences corresponding to the two vehicle models. Due to the moving vibration mass model is closer to the actual condition, it is necessary to consider the vibration characteristics of vehicle in the analysis of vehicle -floating bridge dynamic responses.
