摘要：
To overcome the cumbersome of the vehicle-bridge interaction system when imposing road roughness, a fast-modeling method for the vehicle-bridge interaction system was proposed. The bridge displacement and the road roughness were applied to the vehicle system as the boundary condition. The vehicle loads were applied to the bridge system as the input. The interaction between the vehicle and the bridge was achieved simply and effectively. To verify the accuracy of the proposed method, a two-dimensional simulation model for the vehicle-bridge interaction system considering the vehicle speed and the road roughness was established, and the simulation results were compared with the theoretical solution. The results show that the bridge displacement error is less than 2%, and the bridge acceleration error is only about 4%, indicating that the proposed method can simulate the vehicle-bridge interaction system fast and accurately and the road roughness can be simulated effectively. It provides new guidance for modeling the vehicle-bridge interaction system. © 2022 Southeast University. All rights reserved.
