摘　　要：工程中实际的循环对称结构,往往因不能理想地循环对称而成为拟循环对称结构。应用广义模态综合法对拟循环对称结构进行振动分析,探讨拟循环不对称结构与循环对称结构振动规律的差异。可为进一步研究循环对称结构提供一定的参考依据。In engineering practice, the cyclic symmertric structures usually are quasi-cyclic symmertric structure; for their cyclic symmetry is non-ideal. Using generalized modal synthesis method to analyze vibration of the quasi-cyclic semmertric structure with additive mass or some constraint, derivates frequency equation and displacement reponse of the structure. Relation between cyclic semmertric structure and quasi-cyclic symmertric structure is obtained, and so it may be used to further research.
