摘要
运用桥梁结构动力学和车辆动力学的研究方法,将车辆和桥梁作为联合动力体系,以在建的武广客运专线廊步特大桥为研究对象,对该桥在高速客车行车条件的动力响应进行了分析,着重分析了单线和双线行车时桥梁在不同列车运行速度下的竖向和横向动力响应。
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.
