| 摘 要： | 将杂交子结构法和组合模态综合法辅之以群表示论来分析循环对称结构流固耦合振动问题,使相应的特征方程的阶数大规模地降低,从而达到简化计算,节省机时,减少内存和初始值输入之目的。对C_6结构进行了计算和实验,计算结果与实验值基本吻合。

| Abstract: | Combining the theory of group representation with the hybrid substructure method and composite modal synthesis method; analyzes the fluid-structure coupling vibration of circular symmetric structure.Thus, the number of order of corresponding eigen equation is reduced, the calculation is simplified, the computational time and initial data input are decreased. The C_6 structure as an example has been calculated and experimented, both obtained results are basically coincident. |
