分析了不同转移轨道间的性能指标,以黄道面与白道面交线作为庞加莱截面实现不同系统轨道的拼接,利用其中耗能最小的日地系稳定流形和地月系的不稳定流形设计了一条低能耗转移轨道。最后对不同轨道进行了能量分析和对比,优化了国内提出的低能探月轨道。仿真结果表明,文中方法比直接通过霍曼转移节约21.1%的能量,对探月工程的轨道设计具有一定的参考意义。
The performance indexes of different transfer orbits are analyzed. Intersection of the ecliptic and white pavement is taken as the Poincaré section to realize the splicing of different system orbitals. By using the stable system of day-earth system and the instable flow of earth-moon system Shape design of a low energy transfer orbit. Finally, the energy analysis and comparison of different orbits have been carried out to optimize the low-energy lunar orbit proposed by China. The simulation results show that the proposed method can save 21.1% of the energy compared with the direct transfer through the Hohmann transfer, which is of certain reference significance for the orbit design of the lunar exploration project.
