| Abstract: | A coupled dynamic model of train-track-bridge was established using the theory of train-track-bridge coupled vibration.Taking the scheme of a suspension bridge（main span：1 120 m）for example,it was analyzed the dynamic properties of the bridge,track and train when assuming that ICE3 train was moving on the suspension bridge at a speed of 160～300 km/h;it was also compared that the dynamic responses of the bridge and the train on condition of the main cable and hanger subjected to different cable forces. |
