Simulative analysis of vehicle-bridge vibration by mode method
The free vibration mode of the bridge and normal coordinates are taken as displacement functions of the bridge vibration. By coupling the vehicle and the bridge as one composite system, the total potential energy of the vehicle and bridge structure under normal coordinates are calculated. Based on the principle of the total potential energy with stationary value in elastic system and the setin-right-position rule for forming structural matrices, the vibration equations of vehicle-bridge time varying system are established and solved. This method could reduce the degrees of freedom of the vehicle-bridge system and required computing time considerably. The vehicle-bridge vibration responses of a continuous truss girder bridge are calculated.
