| Abstract: | By combining the static substructure method and the direct superposition of Ritz vectors,a new method for dynamic analysis of structures is presented in this paper.Com- paring with dynamic substructure method,it has three main advantages:1.No error exists in the analysis stage of substructure,because the static substructure method is an accurate nethod.2.Eigenvalue problems do not appear in the analysis stage of substructure.There- fore,the computation time for the dynamic analysis of structure can be reduced.3.The umber of reduced eigenvalue equations of structure is only equal to the number of Ritz vectors,and is independent of the degrees of freedom on interface between substructures. |
