Abstract:: Aiming at the complexity of the analysis of vehicle-bridge coupled vibration response of highway bridges, combined with the principle of separation iteration method and vehicle dynamics theory, a numerical analysis method of vehicle-bridge coupled vibration response based on ANSYS is proposed. The vehicle model and bridge model are independently built in ANSYS software In the environment, use the constraint equation to realize the displacement coordination relationship between the wheel and the bridge deck contact point at any time (the force balance relationship is automatically satisfied), based on the ANSYS transient dynamics solution function, use APDL programming to realize the coupled dynamics of vehicles (traffic flow) passing the bridge The time-history response analysis was carried out, and a quantitative comparison was made with the results of relevant literature examples. The research results show that the accuracy of this method is relatively high. The response trend is basically the same; this method does not need iterative calculation at any load step, which avoids complex program design and greatly improves the analysis efficiency.
