| Abstract: | The structure of the modern spacecraft is very complicated either for the calculation analysis or the test analysis. Thus the substructure modal synthesis method appeared. This paper systematically reviewed and summed up the development and progress of the three kinds of substructure modal synthesis, and also introduced application of this method in aerospace engineering. The method can improve the efficiency of the spacecraft design. Finally, problems in application of the substructure modal synthesis method is mentioned. |
