Abstract

Abstract: In order to solve the problem that the vibration response of the vehicle-bridge coupling vibration model can not be analyzed completely,through the use of SIMPACK software flexible rail module and the self-made rail *.ftr file,a new method based on SIMPACK and ANSYS is proposed.Then,by using the coupling method to establish the vehicle-floating slab track coupling vibration model,and the displacement response of the rail and the floating slab is analyzed.The analysis results are compared with the existing results,and the results show that the method is correct;Ultimate,a coupled model of train,track,U-girder and pier is established by taking the simply supported U-girder bridge as the research object,and the vibration response of the bridge system is simulated.The results show that the vibration response of the vehicle bridge system can be fully analyzed by the improved method,and the analytic results can provide a reference for the design of the bridge vibration reduction.

Key words: vehicle-bridge coupling, structural vibration, multi-body dynamics, finite element, simulation, SIMPACK, ANSYS
