| Abstract: | The lateral amplitudes of part bridges on Jinwen line exceed the limit value of traffic safety given by code.In order to take proper measures on these bridges,the train running performance of these bridges is needed to be evaluated urgently.The calculation model for train-bridge system vibration was presented,and train running performance of four bridges was analyzed with energy random analysis theory for derailment.The analyzed result shows that the safety,comfort and smoothness of running train on Wuyijia... |
