| Abstract: | The idea of Double Compatible Dynamic Substructure Technique is extendedto mode synthesis of Cn group symmetric structures. A free-interface modesynthesis method which is coordinate with the algorithm of representation theoryof finite group is provided for rapid extraction of the natural mode of rotationallyperiodic systems. It collects the residual mode contributions of various substruc-tures, and then eliminates all interface degrees of freedom of the basic "sector".Hence this accurate dynamic reduction further raises the efficiency of dynamicanalysis. |
