| Abstract: | The Lang-bu Bridge is being built on the passenger dedicated railway line from WuHan to GuangZhou. In this paper, using the method of bridge structural dynamics and vehicle dynamics, regarding the vehicle and the bridge as a combined vibration system, the dynamical responses of this bridge to bullet train loads are researched. The vertical and transverse dynamical responses of this bridge when taking monoline and crewel bullet train loads at different speed are researched. |
