| Abstract: | Aiming at new Changsha station on Wuhan-Guangzhou passenger special line,the train-bridge sub-model and bridge-station sub-model were established.Through analyses and calculations for the train bridge dynamic interactions,the load time historys acting on the nodes of track beam by running train were obtained,then take the loads as the external excitation acting on the bridge-station sub-model for the time history analysis.Detailed vibrations analysis of waiting room's floor was presented on the following as... |
