摘　　要：针对未来地月空间中转站的建设需求,进行中转站轨道选择与转移轨迹设计。基于地月空间周期轨道,综合考虑轨道构型、稳定性等因素,选定L_(2)点的南近直线晕轨道(NRHO)作为目标轨道。针对NRHO稳定性强、转移难以实现的问题,基于三体Lambert算法通过月球借力从奔月轨道转移到NRHO。为克服NRHO无明显流形结构的缺陷,基于Cauchy-Green张量提出相空间主拉伸方向理论,进而拼接Lambert段与沿主拉伸方向的反向积分轨迹,获得施加转移脉冲的最有效方向,求解低能转移轨迹。研究结果表明,月球借力转移可以用于载人探月,Lambert拼接法能有效缩短低能转移的时间,为中转站货运提供轨道参考。To meet the needs of constructing future Earth-Moon space station,the orbit selection and transfer trajectory design of the station has been implemented.Based on the Earth-Moon space peri-odic orbits,the southern L2 near-rectilinear halo orbit(NRHO)is selected as the target orbit by comprehensively considering the orbit configuration and stability.Considering the high stability of NRHO and the difficulty to transfer,the optimal transfer from the lunar transfer orbit to NRHO is de-signed based on the three-body Lambert algorithm through the lunar gravity assist.To overcome the defect that NRHO has no obvious manifold structure,the theory of the principal stretching direction in phase space based on the Cauchy-Green tensor is proposed to obtain the most effective impulse ex-erting direction,and then the low-energy transfer trajectory is derived by patching the Lambert seg-ment with the inverse integral trajectory along the principal stretching direction.The research results indicate that the lunar gravity assist transfer can be used as an ideal orbit for manned transfer,and the low-energy transfer trajectory using the Lambert patching method can effectively shorten the transfer time and provide a reference for the cargo spacecraft to the space station.
