A Mars rover wheel endurance testing stand

Abstract

The invention discloses a Mars rover wheel endurance testing stand composed of a rack, a soil tank, a control system and a transmission system. The rack is arranged on the soil tank; the control system is fixedly arranged on the upper end of the rack; the upper end of the transmission system is fixedly arranged on the rack; and the lower end of the transmission system is arranged on the soil tank. Before the test, a model wheel is mounted on a motor shaft; the wear test, working time and working energy consumption under different conditions are simulated by changing the angle between the wheel and the soil tank, the load size and the rotating speed to obtain durability test results. The working time and working power consumption are displayed on a display panel in real time, and an endurance test result is obtained. The Mars rover wheel endurance testing stand of the invention is simple to operate, and is safe and reliable. The Mars rover wheel endurance testing stand can examine the durability of a Mars rover wheel under different road conditions, realizes an effect of multiple test conditions, increases test diversity and can output data such the test rotary speed, the test time and energy consumption through a data collector so as to facilitate recording.

Description

technical field [0001] The invention relates to the field of Mars exploration, in particular to a durability test bench for wheels of a Mars rover. Background technique [0002] Mars is covered by a layer of loose granular material, and the surface is covered with craters, volcanoes, sand dunes and canyons. In addition, the rock distribution density on the surface of Mars is high, with a coverage rate of about 14%-16%. The Curiosity rover The thickness of the wheel surface is 0.8mm. After running on the surface of Mars for a period of time, cracks and holes appear on the surface of the wheel surface, which seriously affects its working life and passability. The durability of my country's Mars rover wheels poses a challenge. Therefore, it is necessary to conduct experimental research on the durability of my country's Mars rover wheels. Under the durability test. Contents of the invention [0003] The purpose of the present invention is to solve the problem that there is no t...
