介绍了车桥耦合动力学分析的主要特点、常用求解算法与理论模型。通过建立斜拉桥桥面的动力学数学模型，求解了桥面的一阶固有频率。利用ANSYS对斜拉桥进行了模态分析、谐响应分析以及瞬态动力学分析。 The paper mainly introduces the characteristic, common algorithm and theoretical model of dynamics of vehicle and bridge coupling. Through establishing the dynamic mathematical model of cable stayed bridge, it solves the first order natural frequency of bridge. Using ANSYS to do modal analysis, harmonic response analysis and transient dynamics analysis for cablestayed bridge.
