摘　　要：针对木星系多目标探测任务,对木星及其卫星系统的探测目标及工程约束进行了梳理和分析,在此基础上提出了3种候选轨道设计方案,以实现对木星极区、木星表面精细结构以及木星伽利略卫星的探测。利用改进的协作进化算法对木星系内引力辅助转移轨道进行了设计与优化,最终得到3种轨道方案的总速度增量分别为3.47km/s、2.95km/s和2.48km/s,其中:方案一能够满足所有探测目标,方案二具有更低的辐射总剂量,方案三能够实现对木星极区及伽利略卫星的多次飞掠探测。上述3种候选轨道设计方案可为未来我国首次木星系探测任务的实施提供参考。In this paper,the primary targets and engineering constraints of a Jovian system multitarget explorationtour phase in a future Jovian system exploration and planet flyby mission are analyzed.Three candidate trajectory design schemes for the Jovian system tour are proposed to realize the detection of Jupiter's polar regions,surface fine structure and Galilean satellites.Then an improved collaborative evolutionary algorithm combining particle swarm optimization and differential evolutionary algorithm is employed to optimize the gravity-assist transfer trajectory.The total velocity increments of the three transfer schemes are 3.47 km/s,2.95 km/s and 2.48 km/s,respectively.The first transfer scheme meeting all three exploration targets,the second having lower total dose of radiation,and the third enabling multiple fly-by detection of Jupiter's polar regions and Galilean satellites.The three candidate trajectory design schemes can provide valuable reference for China's first Jovian system exploration mission.
