Abstract:
The rotation and overturn of vehicle in longitudinal direction were considered, and the process of heavy vehicle passing bridge-tunnel section was regarded as forced oscillation under certain initial condition. Based on D'Alembert principle, the calculating model of vehicle-road dynamic coupling was built, and vibration equation was given. The impact response of vehicle was analyzed by using Laplace transform, the change law of maximum impact force of vehicle on road was got. The influences of vehicle load, goods position, vehicle speed, difference settlement on vehicle impact response were researched. The test acceleration value was obtained, and the calculated result of acceleration was verified. Analysis result shows that this impact forces between vehicle and road increase with the increases of difference settlement, vehicle speed and load, the influences from big to small in order are vehicle load, difference settlement, vehicle speed. The goods position has little influence on vehicle impact force. 7 figs, 15 refs.
