利用太阳帆能在三体问题中实现人工拉格朗日点,人工拉格朗日点克服了经典拉格朗日点位置固定的缺点,研究人工拉格朗日点的被动控制对深空探测有重要的意义。理论上人工拉格朗日点都不稳定,研究表明在被动控制下存在某些人工拉格朗日点的稳定特性与稳定平衡点非常接近,在工程上可以认为稳定。被动控制可以通过设计太阳帆来实现,本文给出了被动稳定太阳帆的设计,在该设计下考虑轨道和姿态的耦合动力学方程。基于该耦合方程研究了人工拉格朗日点的稳定性。仿真结果表明被动太阳帆使得人工拉格朗日点稳定。
The artificial Lagrange points can be generated by the solar sail.They can overcome the drawbacks of the classical Lagrange points,which are fixed in the rotating frame.The stability analysis of the points will benefit the deep space exploration greatly.There are no stable artificial Lagrange points theoretically,however,some points are very similar with the stable points.They can be regarded as stable in engineering.The passive sail design is discussed and the attitude and orbital dynamics is used to analy...
