摘要: 为准确分析车桥之间的相互作用,根据达朗贝尔原理推导出了车桥系统动力平衡方程。通过位移协调方程及 车桥相互作用联系方程,将车桥两系统耦合起来并通过ANSYS 实现。数值算例表明:运用基于ANSYS 车桥耦合动 力分析方法所得结果与利用振型叠加法所得结果吻合良好,表明该方法是正确而有效的,可用于分析各种车桥耦合 振动问题。

关键词: 车桥耦合, 振动, 数值算法

Abstract: To analyze the dynamic interaction between bridge and vehicle accurately,the dynamic balance equation of vehiclebridge coupling system is deduced by the D’Alembert method.By coupling of vehicle vibration and bridge vibration with compatibility equ-ation of displacement and contact equations of vehicle-bridge interaction,equations of vehicle-bridge coupled vibration are established and implemented with ANSYS.The results are identical to those from superposition method of vibration mode,and it proves that the algorithm is valid and effective enough to analyze the vehicle-bridge coupling vibration system.

Key words: vehicle-bridge coupling, vibration, numerical analysis method
