ABSTRACT = {Aiming at the problem that it is difficult to obtain the explicit expression of the structural matrix in the traditional train-bridge coupling vibration analysis, a combined simulation system of train-bridge coupling system (TBCS) under earthquake (MAETB) is developed based on the cooperative work of MATLAB and ANSYS. The simulation system is used to analyze the dynamic parameters of the TBCS of a prestressed concrete continuous rigid frame bridge benchmark model of a heavy-haul railway. The influence of different driving speeds, seismic wave intensities, and traveling wave effects on the dynamic response of the TBCS under the actions of the earthquakes is discussed. The results show that the bridge displacement increase in magnitude in the lateral direction is more significant than in the vertical direction under the action of an earthquake. The traveling wave effect can significantly reduce the lateral response of the bridge, but it will significantly increase the train derailment coefficient. When the earthquake intensity exceeds 0.2 g, the partial derailment coefficient of the train has exceeded the limit value of the specification.},
