| Abstract: | Bond graph is used for the analysis and research of the dynamic substructure. Substructure acquired its corresponding eigenvector and eigenvalue by this method. Besides that, this paper brings forward a new basic principle for the free interface mode of substructure, and deduces a calculating approach for the free interface mode of two substructures modal synthesis. The sample calculation shows that the free interface mode method of synthesis based on bond graph has not only many significant advantages of convenience, high efficiency and exactness, but also guarantees the identity of the bond graph model whether before the integral structure being segmented or after that being synthesized. |
