浅层月壤微定量采样铲设计与试验

Shovel Design and Testing for Micro-Quantitative Sampling of Shallow Moon Soil

  • 摘要: 基于月球极区月壤挥发物丰度原位高精度分析对测试样本微量定量的要求,提出一种基于机械臂末端搭载的采样铲方案,由渐进式铲挖方式构建浅层月壤剖面,通过定容采样腔构型实现既定深处月壤样品微量定量采集,并在极端情况下可由铲齿刮取月壤水冰形成碎屑进行样本采集。为验证采样方案的可行性,搭建了模拟月壤剖面铲挖采样效能测试平台,开展了渐进式铲挖、定容式微量采样和振动式送样试验,试验结果表明采样铲具有130 mm深度剖面构建能力与200 ±30 mg 微定量采样性能。研究成果可为中国月球极区月壤原位采样探测分析任务提供方案借鉴。

     

    Abstract: In situ high-precision analyses of volatile abundance in lunar soil in the lunar polar regions require micro-quantification of test samples. In this paper, a sampling shovel scheme based on the end of a robotic arm was proposed. A shallow lunar soil profile was constructed by progressive shovel digging, micro-quantitative collection of lunar soil samples at fixed depths was achieved through the configuration of a fixed-capacity sampling chamber, and the shovel teeth could be used to scrape the debris formed by the water ice of the lunar soil for sample collection in extreme cases. To verify the feasibility of the sampling scheme, a simulated lunar soil profile shovel-digging sampling efficiency test platform was built, and progressive shovel-digging, fixed-capacity micro-sampling, and vibratory sampling tests were carried out. These tests show that the sampling shovel has the capability of constructing a 130 mm deep profile and a 200 ± 30 mg micro-quantitative sampling function. The research results provide a feasible scheme for the exploration and analysis of China’s lunar soil sampling in the polar regions of the Moon.
