| Abstract: | A dynamic modeling of solar sail spacecraft deployment mechanism is investigated in this paper.Firstly,a general dynamic model for solar sail spacecraft deployment mechanism is derived by using the hybrid coordinate and component modal synthesis.The model and flexible coupling coefficients developed can be used for analysis and simulation of many Solar Sail Spacecraft deployment mechanism.Finally,the effectiveness of the proposed method is demonstrated by an example. |
