Problems solved by technology

If a variety of raw materials and granulation methods are used to prepare heterogeneous materials to simulate lunar soil, in addition to the disadvantages of high production cost and long production cycle, problems of uneven mixing and specific gravity segregation are prone to occur during the large-scale preparation process, which is serious. Affects the consistency of simulated lunar soil mechanical properties

Abstract

The invention discloses a simulated lunar soil for engineering and a preparation process thereof. Cinerite in Jinchuan District, Huinan County, Jilin Province is selected as the raw material of the simulated lunar soil; the simulated lunar soil is prepared from nine types of cinerite of 3 meshes, 4 meshes, 8 meshes, 10 meshes, 18 meshes, 40 meshes, 60 meshes, 160 meshes and 200 meshes according to respective weight percentages. The preparation process of the simulated lunar soil comprises the steps of raw material selection, scoria air-drying, scoria coarse crushing and drying, scoria pulverization and finished product preparation. The simulated lunar soil prepared through the preparation process of the invention meets the requirements of the simulated lunar soil for engineering in both preparation cycle and control indexes.

Description

technical field [0001] The invention relates to a simulated lunar soil for engineering and a preparation process thereof. Background technique [0002] my country's recent plan for lunar exploration is aimed at unmanned lunar exploration. The lunar surface inspection probe will land on the moon in 2013 with the Chang'e-3 lander. The lunar surface inspection probe is a spacecraft that can move on the surface of the moon and complete tasks such as detection, sampling, and delivery. Its basic function is to have the ability to walk on the lunar surface. Before landing on the moon, it is necessary to conduct comprehensive tests on the traction, passability, and maneuverability of the lunar surface inspection probe in a simulated lunar environment to avoid risks. The simulated lunar soil for engineering is the working medium for the infield test of the rover, so it is of great significance to determine a reasonable preparation process for the simulated lunar soil for the infield...
