Abstract:
A differential equation of coupling vibration between a four degree moving vehicle model with uniform acceleration and bridge was advanced by mainly considering both influences of interia of force of moving vehicle and its acceleration on vertical vibration.The principle variation of bridge deflection was calculated with two variable parameters: the intial speed and the acceleration of moving vehicle by using the method of finite element. The results show that the the intial speed and the acceleration of moving vehicle have great influence on the dynamic amplification factor of bridge, the bridge dynamic amplification factor increases with the increasing of vehicle initial speed, but increases initially, then decreases with the increasing of vehicle acceleration, and there is an extremum region. 8 figs, 12 refs.
