摘要
通过建立客车与无推力式钢桁系杆拱桥的车桥耦合动力分析模型,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。本文分析了无推力式钢桁系杆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。
Through building vehicle-bridge coupling dynamic analysis model between train and arch bridge without thrust, and based on 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 arch bridge without thrust are analyzed and the train running safety and passenger riding comfort are studied.
