| Abstract: | The attitude motion of solar wings on spacecraft with a flexible shaft in gravitational field is discussed in this paper. The generalized potential energy of spacecraftsystem is derived. The stability of relative equilibrium of solar wings on spacecraftwith a flexible shaft in the orbital plane is determined by use Liapunov's directmethod. A sufficient condition of stability on spacecraft is obtained, and the influence of the torsion stiffness of a flexible shaft and the mass geometry of solar wingson the attitude stability is analysed. |
| Keywords: | Attitude stability Flexible shaft Liapunov's direct method |
