Aerodynamic characteristics of a high-speed train travel on the bridge

摘要：

　　The present paper reports a numerical investigation on the aerodynamic performance of a CRH2 high-speed train and bridge system under the strong cross wind.Effects of the train running speed on the train-bridge system were addressed comprehensively.For a running train,the aerodynamic drag and overturning moment on the head coach are larger than those on the other coaches,especially the trailing one.Reynolds number has significant effects on the train-bridge system with the yaw angle of oncoming wind of 42° and 90°.With the increase of the train running speed or the yaw angle of oncoming wind,the drag and lift of both the train and the bridge increases gradually,especially those on the head coach of the train.
