针对地月拉格朗日L1点流形无法到达地球附近的问题,介绍了基于扰动流形的L1-地球转移轨道设计方法,首先构造了扰动流形的参数化形式,通过搜索四维参数空间,给出了多种经过数值优化的转移轨道,在总结数值仿真结果的基础上提出采用轨道角动量定性分析轨道转移机理的方法,明确了L1-地球转移轨道的设计应以降低轨道角动量为目标,克服了以往优化方法搜索的盲目性,揭示了转移轨道所依据的动力学特征,最后给出了基于轨道转移机理设计的低能转移轨道,证明了该方法的有效性.
Aiming at the problem that the L1-L1 manifold can not reach the earth nearby, the L1-Earth transfer orbit design method based on the perturbed manifold is introduced. Firstly, the parametric form of the perturbed manifold is constructed. By searching the four-dimensional parameter space, Based on the numerical simulation results, a method of qualitatively analyzing the orbital transfer mechanism by orbital angular momentum is proposed. It is clear that the design of the L1-Earth orbit transfer trajectory should be aimed at reducing orbital angular momentum , Which overcomes the blindness of searching by the optimization method in the past, reveals the dynamic characteristics on which the transfer orbitals are based, and finally gives a low-energy transfer orbit based on the orbital transfer mechanism to prove the effectiveness of the method.
