摘要

摘要: 针对位于椭圆轨道上的绳系系统，利用“圆锥”模型通过仿真研究其动力学运动特性。绳系系统是具有一定面积的主星和子星通过若干根超长的绳索连接而成的结构。基于主星的大面积和绳索的超长度，分别将其建立成两两相连的质量杆和用力连接的小圆柱。在动力学模型的基础上，针对主星和整体系统进行动力学仿真研究。研究表明，系统在椭圆轨道姿态稳定、主星展开正常。在材料范围内较小的绳索伸长使绳索紧绷，省去了展开过程中力的设置。

Abstract: The dynamics simulation of a tethered system located on elliptical orbit is studied by using the so-called "cone" dynamics models. The tethered system is a structure that has a huge area of major satellite and minor satellite connected through some long ropes. On the strength of the huge area of the major satellite and the super length of the ropes, the quality rods and the little cylinder connected with force are built respectively. Based on the dynamic model, the dynamics simulation of the major satellite and the whole tethered system is discussed. The discussion results show that the attitude control of the tethered system on elliptic orbit is stable and that the major satellite extends normally. The tethered system eliminates the need to use force in the process of setting because the rope stretched in its range.
