Test environment for simulating topography and landform of complex Mars landform

Abstract

The invention discloses a test environment for simulating the topography and landform of complex Mars, which comprises seven terrains, namely a coarse sand area, a loose rock area, a sharp-corner rock area, a rounded-corner rock area, a slate area, a medium sand area and a fine sand area, and is characterized in that the coarse sand area is used for simulating the surface flat plain environment of the Mars; the medium sand area is used for simulating a canyon plain environment on the surface of the Mars; the fine sand area is used for simulating a Mars surface sand dune environment; the loose rock area is used for simulating a sand environment with sharp-corner and rounded-corner rocks on the surface of the Mars; the sharp-corner rock area is used for simulating a sand environment with irregular rocks on the surface of Mars; the rounded-corner rock area is used for simulating a sand environment of regular rocks on the surface of Mars; the slate area is used for simulating a mars surface batholith environment. According to the test environment, simulation of the Mars soil environment and the topography and landform is realized, and all test conditions required in the test process and comprehensive requirements on the Mars soil and the surface topography and landform of the Mars are met.

Description

technical field [0001] The invention relates to the field of ground tests in deep space exploration, and more specifically relates to a test environment for simulating complex Mars topography. Background technique [0002] Due to the existence of wind, the topography of Mars is more complex and changeable than that of the lunar surface. It once caused the Mars rover Spirit to fall into the sand dunes and stop working, and the wheels of Curiosity were scratched by rocks and affected its movement. Therefore, in order to better plan and navigate the path of the Curiosity rover, NASA in the United States divides the Martian terrain into five types: Sand, Loose Rock, Bedrock, and Sharp Rock Block ground (Angular Embedded Rock) and round corner stone ground (Round Embedded Rock). But in 2017, researchers from NASA and the University of Washington, based on the above five types of terrain, classified the roads that Curiosity passed through in more detail, which can be divided into...

Problems solved by technology

[0005] In order to solve the problem of the single topography of the existing Mars test environment, according to the latest classification of Mars topography, the size and quantity of stones, and the mechanical parameters of fire and soil, the present invention proposes a test environment for simulating complex Mars topography. The test environment realizes The simulation of the Martian soil environment and topography meets all the test conditions required in the test process and the comprehensive requirements for the Martian soil and the topography of the surface of Mars.
