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。
The use of manifolds near the translational point of the three-body problem to achieve low-energy orbit transfer is a hot issue in current flight dynamics research. Because there is no strict analytical solution to the three-body problem, numerical algorithms are often used to design the orbit. This method is computationally intensive and consumes a lot of time and resources. Based on the existing theory, a new orbit design method based on two-body model and three-body model is proposed here, which can accelerate the orbit matching and search in phase space and improve the efficiency of the whole design process. Finally, a low energy transfer orbit from the lunar orbit to the L1 point Halo orbit of the earth-moon system is realized by this method. Simulation results show that this method is efficient and reliable.
