| 摘 要： | 针对位于日地系统共线平动点附近三维周期轨道上的旋转绳系卫星编队,利用数值仿真研究其重构阶段的动力学稳定性问题。编队系统为一个母卫星和n个子卫星通过长度可变系绳连接的轮辐状结构,基于Hill限制性三体问题建立姿态与轨道耦合的动力学模型,分别针对留位以及包含展开和回收的编队重构阶段,利用非线性数值仿真研究其姿态稳定性。研究表明系统留位姿态稳定,展开不稳定,回收稳定,较小的母卫星轨道高度及绳长变化速度更有利于姿态稳定。

| Abstract: | Simulation of dynamical stability of spinning tethered satellite formations during reconfiguration stage was researched.The system consists of a parent satellite and n subsatellites,connected together in a hub-spoke configuration via variable-length tethers,where the parent satellite follows three-dimensional periodic orbits near the second libration point of the Sun-Earth system.Based on the Hill's restricted three-body problem,a new dynamical formulation was developed,which could be utilized for the nonli... |
