Coupled Dynamics of Liquid-elistic-qrigid of a Liquid-filled Spacecraft with Solar Wings which Has a Flexible Shaft |
|
| Abstract: | In this paper attitude dynamics of liquid-filled spacecraft with solar wings which has a flexible shaft is studied. The dynamics equations of system are obtained by using the theorem of angular momentum. The torsional motion of flexible shaft and vortex motion of liquid in tank are analyzed. The relational equation of attitude angular velocities of the spacecraft, the torsional motion of flexible shaft and vortex motion of liquid in tank are given. The influence of the torsional motion of flexibleshaft and the vortex motion of liquid in tank on the attitude motion of the spacecraft are nanlyzed,too. |
| Keywords: | liquid-filled spacecraft attitude dynamics flexible appendages |
