Under strong excitations, such as earthquake, the effect of the geometric nonlinearity of the suspension bridge is significant. Traditional train-bridge interaction analysis method usually cannot simultaneously consider both geometric nonlinearity and spatial wheel-rail contact. In this paper, an ANSYS-MATLAB co-simulation method is proposed to analyze the dynamic responses of the train-suspension bridge system under earthquake excitation. The two software platforms are coupled through the interaction between track and bridge, and then the dynamic response of the whole vehicle bridge coupling system is solved. the dynamic response of the train-bridge system of a railway suspension bridge under the action of an earthquake is analysed, taking into account the effect of peak ground acceleration and characteristic period on the geometric nonlinearity of the bridge and the safety of trains running on the bridge. |
