This report reviews the most important episodes in the history of designing the self-propelled automatic chassis of the first mobile extraterrestrial vehicle in the world, Lunokhod-1. The review considers the issues in designing moon rovers, their essential features, and the particular construction properties of their systems, mechanisms, units, and assemblies. It presents the results of exploiting the chassis of Lunokhod-1 and Lunokhod-2. Analysis of the approaches utilized and engineering solutions reveals their value as well as the consequences of certain defects.

“发展空间科学,开展深空探测”是我国近期(2010年前后)的航天发展目标之一,月球探测是实现我国“开展深空探测”的第一步。发射月球探测器(或卫星)选择适当的火箭型号显得尤其重要。文章从月球探测工程对运载火箭的基本要求着手,结合国外月球探测工程的经验和长征系列火箭的现状,提出了候选火箭及其改造方案,并且对月球探测三种运行轨道的优缺点和工程的可实现性进行了分析。从航天大系统工程整体化的角度,提出了用长征三号乙加上面级发射环月卫星,同时将上面级实现硬(或软)着陆作为首选方案,用长征三号丙发射探月器进入奔月轨道作为次选方案的建议。

Achieving historically anticipated improvement in the performance of integrated circuits is challenging, due to the increasing cost and complexity of the required technologies with each new generation. To overcome this limitation, the exploration and development of novel interconnect materials and processes are highly desirable in the microelectronics field. Molybdenum (Mo) is attracting attention as an advanced interconnect material due to its small resistivity size effect and high cohesive energy; however, effective processing methods for such materials have not been widely investigated. Here, we investigate the electrochemical behavior of ions in the confined nanopores that affect the electrical properties and microstructures of nanoscale Mo and Mo–Co alloys prepared via template-assisted electrodeposition. Additives in an electrolyte allow the deposition of extremely pure metal materials, due to their interaction with metal ions and nanopores. In this study, boric acid and tetrabutylammonium bisulfate (TBA) were added to an acetate bath to inhibit the hydrogen evolution reaction. TBA accelerated the reduction of Mo at the surface by inducing surface conduction on the nanopores. Metallic Mo nanowires with a 130 nm diameter synthesized through high-aspect-ratio nanopore engineering exhibited a resistivity of (63.0 ± 17.9) μΩ·cm. We also evaluated the resistivities of Mo–Co alloy nanowires at various compositions toward replacing irreducible conventional barrier/liner layers. An intermetallic compound formed at an Mo composition of 28.6 at%, the resistivity of the Mo–Co nanowire was (58.0 ± 10.6) μΩ·cm, indicating its superior electrical and adhesive properties in comparison with those of conventional barriers such as TaN and TiN. Furthermore, density functional theory and non-equilibrium Green’s function calculations confirmed that the vertical resistance of the via structure constructed from Mo-based materials was 21% lower than that of a conventional Cu/Ta/TaN structure.

在探月工程计划中,月球车的车轮系统是月球车总体设计系统的重要子系统之一。由于月表地形复杂,同时受限于月球车有限的空间,因此大大增加了车轮系统设计和优化工作的难度。本研究的主要目标是针对自主设计的月球车机械结构,建立一个原理型样机以对其性能进行优化。研究的主要工作包括:为应对月表复杂路况,提出了一种适配月球车正反四边形悬架的新型叶片伸缩式步行轮;以功耗最小化为目标,在保证障碍通过性的前提下,分析车轮运动过程中受力情况以实现对车轮的性能优化;最后,基于数字仿真和综合实验方法,验证了新型车轮系统在实际实验中可以达到按需伸缩叶片和节约能耗的效果。本文的研究成果为中国月球车的研究和开发提供了一种技术参考。
