摘要
本文提出具有连接区的间接对接的混合界面子结构模态综合法，讨论了位移协调和力与位移双协调两种对接模式。
A new technique of modal synthesis for dynamic analysis of structures is presented inthis paper. Applying the technique,the structure is divided into two kinds of substructure,free-interface substructures and fixed-interface substructures. There are not direct couplinginterfaces between these substructures. However,the substructures are coupled through thelink area. Two coupling ways are suggested,including the single compatibility for displace-ment and the double compatibilities for displacement and force on interfaces. The bettercomputing resuIts can be achieved by considering the effect of the truncated higher modes ofthe free-interface substructures.
