Selenographic environment simulation device used for simulating selenographic drilling test

Abstract

The invention discloses a selenographic environment simulation device used for simulating selenographic drilling tests. The selenographic environment simulation device comprises a vacuum tank system, a vacuum pumping system, a heating and refrigerating system and a data acquisition and control system, wherein the vacuum tank system comprises a vacuum tank, a lunar soil barrel, a lunar soil barrel rotating mechanism and a lunar soil barrel locking mechanism; the vacuum pumping system comprises a vacuum pump sets, a cooling water circulator, an air compressor, a vacuum pump set control cabinet and a corrugated pipe; the heating and refrigerating system comprises a heating device and a refrigerating device, and an internal cooling circulation part of the entire refrigerating device is arranged in a vacuum container; and the data acquisition and control system comprises a temperature module and a vacuum measuring module. The selenographic environment simulation device reasonably selects an environment simulation item aiming at the sensibility of thermal characteristics on selenographic environment factors in the drilling process, and simulates an effective selenographic test environment for the drilling test including high vacuum, high surface temperature, low temperature below the surface, ignores the environment simulation items which has almost not effect on test results, and is economical and effective.

Description

technical field [0001] The invention relates to a lunar surface environment simulation device. The device can simulate the environmental characteristics of high vacuum on the lunar surface, high temperature on the surface of the lunar soil, and low temperature below the surface. The simulated lunar soil at different positions in the cylinder is used for drilling test research, which belongs to the field of space resource detection technology. Background technique [0002] The mission of the Lunar Exploration Project (Phase III) project is to launch an unmanned lunar lander, conduct drilling and surface sampling on the lunar surface, and bring the collected lunar soil samples back to Earth. In order to complete the drilling and sampling tasks, it is necessary to design the drilling mechanism and conduct a series of research on the nature of drilling to provide relevant knowledge reserves for the tasks of the lunar exploration project (Phase III) to ensure the safety and relia...

Problems solved by technology

The large difference between the ground and lunar surface environments may cause a large deviation between the ground test data and the lunar surface test data. The ground test results may have a misleading effect on the reasonable setting of the drilling device parameters and the improvement of the mechanism performance, and it is not easy to find Some major hidden dangers
