Description

Technical Field

[0001] This invention relates to the fields of aerospace engineering test equipment and ground simulation experiments for lunar engineering activities. More specifically, it relates to a simulation experiment device for lunar resource mining and in-situ construction and its working method. Background Technology

[0002] With the continuous advancement of my country's lunar scientific exploration missions, lunar scientific research is gradually shifting from surface features to the intrinsic nature of the moon, from understanding the moon to utilizing it, and from ground-based research to in-situ research. The moon possesses abundant resources, and its development and utilization can ensure long-term human habitation on the lunar surface, reduce dependence on Earth for material and energy supplies, support future manned lunar exploration, lunar surface exploration, and the construction and sustained operation of lunar bases, and is of great significance for seizing the initiative in space resource development.

[0003] Major projects such as manned lunar exploration and lunar surface activities, lunar exploration, and the construction of future lunar bases require engineering activities including lunar resource extraction, engineering construction, and waste disposal. To ensure the smooth implementation of lunar engineering activities, relevant technologies need to be verified on the ground, necessitating the construction of targeted ground testing facilities.

[0004] Current experimental devices for simulating the lunar surface environment are relatively mature, but most focus only on reconstructing vacuum and large temperature difference environments, serving static tests such as spacecraft construction and material performance testing. They lack dynamic experimental devices specifically designed for lunar engineering activities such as lunar construction and lunar resource extraction. In summary, the following problems exist in the development of simulation experimental devices for lunar resource extraction and in-situ construction: 1) Due to issues such as vacuum sealing and temperature environment, most studies are static simulations, making it difficult to conduct dynamic simulations of engineering operations; 2) Most of the simulations are for single engineering operations under extreme lunar environmental conditions, making it difficult to evaluate and simulate multiple types of engineering operations; 3) Due to space limitations and limited functionality, it is difficult to simulate procedural engineering operations. 4) Most of the work is based on a single type of energy source, making it difficult to achieve the effect of multi-energy source and mechanical collaborative work.
