摘　　要：本文提出利用结构的假想中间联接单元和假想联接刚度的概念,用一种新的模态刚度的组集方法求得结构在弹性联接下的模态综合方程,并将该方法应用于弹性联接的双转子系统的计算中。In this paper, the authors introduce a fictitious interconnecting system by using its fictitious link stiffness, and present a new modal stiffness coupling method. In this case, the equatin of component modal synthesis under elastic—connecting is established. This method is applied to calculate a two rotors system under the elastic—connecting condition.
