| 摘 要： | 在循环对称结构受迫响应分析的基础上,从理论上探讨了外载荷不同分布作用下结构的模态特征和位移特性。从而为循环对称结构的多点激振试验、模态分析和载荷识别提供理论依据,并且为模态分类提供一种有效的方法。

| Abstract: | Based on the analysis for forced response of circular symmetric structures,the mode and displacement characteristics of these structures under different load distribution are studied theoretically by generalized modal synthesis method.The result provides theoretic basis for the multi-point excitation experiment,the modal analysis and the load identification.In the external forces designing, it may be used to select resonable distribution to avodid resonance emerged in the working structure. |
