Problems solved by technology

However, due to different engineering purposes, these simulated Martian soil schemes are also quite different, and a unified standard has not yet been formed. Due to technical confidentiality, it is difficult to obtain the core parameters of simulated Martian soil, and due to price and technical blockade, it is not produced externally.

Abstract

The invention discloses engineering simulative Mars soil for ground tests of a touring device. The Mars soil is formed by mixing scoria powder of the Jingyu Shuangshan volcano and ilmenite powder, wherein the weight percentage of the scoria powder of the Jingyu Shuangshan volcano is 96%, and the weight percentage of the ilmenite powder is 4%. The particle morphology of the simulative Mars soil is similar to that of Mars soil. The spectral change curve of volcanic ash of the Jilin Jingyu Shuangshan volcano is similar to that of Olympus-Amazonis. The volcanic ash of the Jilin Jingyu Shuangshan volcano is red which is closest to the color of weathered materials on the surface of Mars. The engineering simulative Mars soil guarantees that the ground tests are carried out smoothly and various tests are reliable, and enables Mars exploration plans to be smoothly carried out.

Description

technical field [0001] The invention relates to an engineering simulated Martian soil used for the ground test of a patrol device. Background technique [0002] In order to ensure the passability of the Mars surface patrol, Martian soil sampling and soft landing tasks, it is necessary to simulate the Martian surface environment on the ground, so as to complete the test and assessment of related performance, such as passing performance tests, path planning, autonomous Verification tests such as navigation, surface sampling and drilling sampling. [0003] For the future Mars exploration plan, the potential landing site of the Mars lander is in the vast plain area within the range of 0-30° north latitude. In order to ensure the safe landing of the Mars lander and the safe and reliable passage of the rover on the surface of Mars, the developed simulation The Martian soil mainly focuses on simulating the mechanical properties and physical properties of the Martian soil, followed...
