Abstract:
Aimed at the influence of girder stiffness decline on vehicle-bridge coupled vibration, a vehicle-bridge coupled vibration numerical analysis method was presented based on ANSYS. The bridge and vehicle model were established separately and APDL language was used to realize coupled vibration relationship between them to get the vibration time-history response curve. Through the comparison with some references, the correctness of this method was proved. The arithmetic was used to analyze the response of vehicle-bridge coupled vibration with the change of vehicle speed, stiffness decline length and stiffness degradation ratio. The 3D change curved figures of impact factor and peak acceleration were got and the influence of each parameter on vehicle-bridge coupled vibration was analyzed. The results show that the deviation of the new method is less than 1% compared with the traditional one. When the stiffness of main girder decline, the maximum deflection impact coefficient is 0.168, while the moment is 0.239. Meanwhile, the maximum vehicle vertical acceleration is 0.973 and the one in midspan section is 1.354. The parameters of vehicle-bridge coupled vibration of simply supported beam will be influenced greatly by driving speed, but little by girder stiffness decline. 2 tabs, 14 figs, 15 refs.
