摘要
综述了月球钻探取样钻具的发展现状,金属三维点阵的轻量化以及激光选区熔化制造技术的基本方法和优势。基于激光选区熔化制备技术提出了将三维空间点阵结构应用于月球钻探取样钻具的轻量化,讨论了点阵结构的钻具对于月球钻进过程的适应性并展望了轻量化月球取样钻具方面的发展趋势。分析认为,利用激光选区熔化技术制备的三维点阵结构在月壤取样钻具方面具有很大的应用潜力。
In this study,the feasibility of applying the lattice structure fabricated by selective laser melting to drilling tools is analyzed.The development status of lunar drilling sampling tools,the lightweight 3D metal lattice structures and the basic methods and advantages of selective laser melting technology are summarized.It is proposed to apply the 3D lattice structure to manufacture lightweight lunar drilling sampling tools with selective laser melting manufacturing technology.The adaptability of the drilling tools of the lattice structure to the lunar drilling process is discussed and the development trend of lightweight lunar drilling tools is envisioned.The analysis shows that the 3D lattice structure prepared by selective laser melting has great application potential in lunar drilling sampling tools.
