| Abstract: | Bond graph was introduced into the analysis and study of a dynamic minor structure,and the cardinal principles of new free boundary mode synthesis was put worward.The calculation method for the free boundary mode synthesis of two minor structures was developed and their corresponding characteristic spectral matrix and vibration mode matrix were obtained.An example given in the paper shows that free boundary mode synthesis using bond graph is very convenient and effective.The results are accurate and reliable;the natural frequency of the whole structure before it was divided into minor structures is the same as that after the minor structures were integrated. |

| Keywords: | bond graph mode synthesis minor structure |
