This paper builds bridge models using PYTHON language based on ABAQUS, embeds the vibration equation of vehicle model into the modeling and loading procedure of the bridge, and solves the vehicle equation by taking advantage of the numerical analysis ability of PYTHON. A single finite element software is utilized in the whole solving process, which avoids interaction call between different softwares. Zhai Algorithm explicit integration method is adapted to predict the vertical dynamic response in the next step according to the dynamic response (vertical displacement, vertical velocity) function of the vehicle and bridge in current analysis step. This method is able to calculate the interaction force between the vehicle and bridge in coupled vibration, improve the computing accuracy and reduce calculation work at the same time. The proposed analysis model is verified through an example with respect to coupled vibration. |
