| Abstract: | In this paper, the dynamic equations for a coupled rigid-flexible space platform consisting of a central body and flexible appendages are derived by use of the hybrid coordinate method according to the Lagrange′s equations. The space platform is regarded as connecting some flexible appendages in central body. The central body performs orbit motion, appendages moves relatively to the central body. The behavior of flexible bodies undergoing large rigid-body motions and small elastic vibrations is a subject of major concern in the field of flexible multi-body system dynamics. The method proposed in this paper can be used for modeling and designing of coupled rigid-flexible multi-body spacecraft. |
