中文摘要：
利用三体问题平动点附近存在的流形实现低能耗轨道转移是当前飞行动力学研究中的热点。由于三体问题没有严格的解析解,因此往往采用数值算法来设计轨道。这种方法计算量大,耗费大量的时间和资源。在已有理论的基础上,这里提出了一种基于二体模型和三体模型相结合的轨道设计方法,在相空间中实现轨道的加速匹配与搜索,提高整个设计过程的效率。最后,利用该方法实现了一条从月球驻留轨道到地月系L1点Halo轨道的低能耗转移轨道。仿真结果表明,该方法是高效和可靠的。
英文摘要：
The design of low-energy transfer trajectory using the manifold near the triangular libration points is a hotspot in today＇s aircraft-dynamics research.Generally numerical methods are used to design the trajectory as the three-body model has no precise analytical solution.However it cost much time and resources.A new method was put forward to solve this problem.Based on the two-body model and the three-body model,the matching speed of the two trajectories in the phase space was improved.Finally a low-energy trajectory from the moon＇s parking orbit to earth-moon system L1 point was designed here.The simulation result showed that this method was efficient and reliable.
