Abstract: Some review literatures on dynamics modeling of flexible spacecraft are presented. The difficulties in modeling large flexible spacecraft are discussed. The problems on deformation description of flexible body, selection of floating reference frame, derivation of dynamic equations and model reduction are analysed.
