    Abstract
  • The third stage of China's lunar exploration project presented the task of drilling samples of lunar soil over 2 m deep, which motivates us to study the thermal characteristics during the drilling process. To support this research, a lunar surface vacuum environmental simulation device was designed. According to the requirements of the drilling test, a three-part and dismountable vacuum chamber was designed which was pumped from the bottom of the chamber. Considering the lunar soil simulant's size and rapid vacuum acquirement requirements, a cribriform lunar soil container with multi-layer filtrations was designed. Based on the demand of repeatable drilling tests in the same condition, the slewing mechanism with missing teeth gear was designed which allowed external operation. Finally, a three-stage diffusion pump set was selected according to the vacuum and dust tolerance requirements. Experimental results show that the vacuum of this simulation device reaches to 10-1 Pa without lunar soil inside, and reaches to 7 Pa with lunar soil inside.These performance indicators satisfy the vacuum requirements of the drilling test. The outgassing amount curve of simulated lunar soil is obtained by measuring the variation of vacuum with time during the pumpout process, which is valuable for the lunar soil vacuum system's application.
