回顾国内外星球钻取采样技术发展现状的基础上,详细论述了星壤的物理力学特性及模拟星壤制备工艺,着重分析了钻进取心特性实验及理论研究成果,深入剖析了包含钻进状态参数辨识及自主钻进控制在内的星球自适应钻进规程关键技术问题.在此基础上,以我国探月三期工程无人钻取采样任务为研究背景,提出了对星球钻取采样技术的展望与建议.
Based on the review of planetary drilling and coring technologies,this paper elaborates the mechanical properties of planetary regolith and the preparation method of the soil simulant.Then,the experimental and theoretical drilling and coring characteristics are analyzed respectively.Meanwhile,the self-adaptive drilling strategy containing the drilling states recognition and autonomous drilling control are carefully researched.Based on the above foundations,the technical prospects and advices have been proposed for China lunar exploration.
