摘要
Abstract
The numerical simulation model to analyze the coupled vibration between vehicle and bridge is established on the engineering background of Yachi River Bridge. The finite element commercial software ANSYS is employed to set up the dynamic analysis model and to compute its natural vibration characteristics. Specific CRH3 model is simulated with multi-body dynamics software SIMPACK. With ANSYS and SIMPACK software, the vehicle bridge coupled vibration simulation system is created and the vehicle bridge coupled vibration is calculated with the input of track-rail irregularity and wheel-rail relation. The analysis results show that the bridge has sufficient stiffness and satisfactory vibration performance, and the train operation safety is guaranteed with stimulated riding comfort. All the calculation results not only provide references for future design of similar bridges but also verify the feasibility and convenience of joint simulation.关键词
