摘要
根据车桥耦合振动理论,并根据势能驻值原理及形成结构矩阵的"对号入座法则",导出了系统的空间振动矩阵方程.分析了大跨度上承式桁架拱桥的车桥动力响应特点,并进行了列车走行安全性与乘客舒适性分析.
Based on the coupled vibration theory,and the variational principle of the stationary potential energy and the'set-in-right position'rule of forming structural matrices,the space vibration equations in matrix form of the system are derived.The properties of vehicle/bridge vibration responses of the long-span deck bridge are analyzed and the train running safety and d passenger riding comfort are studied.
