摘　　要：面向载人月球探测转移轨迹与月面着陆区评估过程中约束繁杂、任务轨道计算与分析效率低、可靠性差等挑战,提出了基于伪状态理论和动态权值策略的载人月球探测任务转移轨道及月面着陆区评估分析方法。利用伪状态技术建立了载人月球探测任务转移轨道优化模型,实现了地月空间三体动力学模型下的高精度地月自由返回轨道和月球返回轨道的快速解算;同时,引入动态权值策略处理任务周期、窗口及速度增量、任务光照、再入返回等工程约束指标,建立了载人月球探测任务代价评估准则,给出了动态权值的取值区间。针对我国未来载人月球探测任务潜在着陆区的数值仿真结果表明,所提方法实现了月球候选着陆区的转移轨迹高效计算与综合代价评估排序。To address the challenges of low computational efficiency and poor reliability in the transfer trajectory design and mission cost assessment for manned lunar exploration,a novel method based on pesudostate theory and dynamic weight strategy is proposed.Firstly,a trajectory optimization model of manned lunar exploration is built using pesudostate technique to improve the efficiency and accuracy of solving the Earth-Moon free return trajectory and Moon-Earth return trajectory.Then,a dynamic weight strategy is utilized to quantify the mission efficiency factors such as mission period,lunch window and velocity increment,and the actual engineering constraints such as mission solar elevation angle and reentry condition.A comprehensive evaluation criterion for the manned lunar exploration program is established,and the ranges of dynamic weights are given through vast numerical simulations.Finally,the numerical simulation results for the candidate landing regions of future manned lunar exploration missions show that the proposed method realizes efficient mission trajectory design and comprehensive evaluation ranking of candidate landing regions.
