| Abstract: |
| This paper focuses on free-interface component mode synthesis methods for damped vibration systems. In order to accurately model the dynamics of the structure, the Residual flexibility matrix is calculated through a weighted-orthogonal matrix formulated in this paper. Since directly calculation of the inverse of the stiffness matrix can be avoided by using this weighted-orthogonal matrix, it is very useful to the synthesis of free substructures. Generalized conforming condition of the interface is discussed. Based on these studies, a new free interface components synthesis method for damping structure is developed. The validity of this method is demonstrated through numerical examples. |
