Abstract:
This paper discusses the applied question in dynamic analysis of combined tress structures. The algorithm is presented about the optimal dynamics design of link substructures, and the synthesis of substructure modes with the accurate residual modes, so that the p low-order natural frequencies of combined truss equal the given values. Numerical examples demonstrate the effectiveness and the applicability of the method. 
