Influence of pier lateral displacement on dynamic response of train-track-bridge coupled system
To improve the safety and comfort of train operation,a coupled system dynamics analysis model of train-track-bridge was established based on the SIMPACK-ANSYS joint simulation platform,with a 4-span 32 m simply supported box girder bridge and an 8-car train as the framework.The simulation calculation and im-pact analysis of the effect of bridge pier lateral displacement on the dynamic response of the train were conduc-ted.The study shows that the lateral displacement of the bridge pier has a significant impact on the vibration response of the train,but not significant on the vibration response of the bridge.When the lateral displacement of the bridge pier exceeds 26.4 mm,the lateral force on the train's axle exceeds the safety limit(62 kN).Therefore,the lateral displacement of the bridge pier should be controlled within 26.4 mm.
