| 摘 要： | 本文从力学变分原理出发,建立了交会对接过程中追踪飞行器与目标飞行器的动力学方程,导出了两个飞行器之间的相对运动方程。以此为基础,讨论了最后逼近阶段的平移过程中,追踪飞行器内部液体的晃动规律,并进一步对飞行器之间的相对运动做了定性分析,论述了液体的晃动对交会对接相对运动中的动力学与控制的影响。

| Abstract: | Beginning from variational principle of mechanics,this paper sets up dynamic equations of chaser and target during the rendezvous and docking,devires equation of relative motion between two spacecrafts,on this basis,discusses the liquid sloshing laws internal to the chaser during the translation of final approach,further makes qualitative analysis for the rela- tive motion between two spacecrafts,and expounds the effect on dynamics and control due to liquid sloshing in the relative motion of rendezvous and docking. |
