| 摘 要： | 把改进了的混合界面模态综合法应用到Ｃ３群对称结构的模态分析计算中，利用Ｃ３群结构的旋转对称性和三个子结构的主模态、剩余模态及约束模态的等同性，通过交介面上的节点的位移和对接力的协调条件，推求出整体结构模态坐标的动力方程。该动力方程的维数低，运算效率高。

| Abstract: | By using the improved mixed interface component modes synthesis method for the modal analysis and computation of C 3 group symmetric structures, and taking advantage of their cyclic symmetric charcter and equivalence of the normal modes, residual modes and the constrained modes of the three substructures, and the harmonize prerequisite of the displacements and butt forces of the nodes on the interfaces, the dynamic equations of the whole structures in modal coordinates are derived. The dimensions of the equations are small and the efficency of the calculation is high. |
