| 摘 要： | 基于边界元方法对边界元中单结合部多分支的结合方法进行了研究，首先建立各个杆件的边界元方程式，然后利用刚性结合，柔性结合或关节结合把各杆件的边界元方程式合并起来，建立整个系统的动力学模型，最后后通过频率扫描方法得到结构的固有频率．

| Abstract: | The paper studies the dynamic analysing method of several beams in one joint based on the boundary element method. First, the dynamic equations of element are established by the BEM, and the dynamic equation of the whole structure of the system is constructed by synthesis of the element. From the dynamic equation of the whole structure, the natural frequency of the whole structure can be obtained by the frequency scanning method. |
