Manned lunar rover wheel soil bin test bed

Abstract

The invention discloses a manned lunar rover wheel soil bin test bed, and belongs to the technical field of spaceflight. According to the invention, rolling wheels of a test trolley are in rolling connection with a U-shaped rail, the front end of a steel wire rope is fixedly connected to a roller of a traction resistance system, and the rear end is fixedly connected with a tension sensor of the test trolley; and a horizontal displacement sensor, a vertical displacement sensor, the tension sensor, a speed reducer assembly and a dynamic torque sensor are all controlled by a computer. According to the test bed, the defects of small size load, low speed, unstable traction resistance and the like of a tested wheel of a small lunar rover wheel soil bin test bed can be overcome; the tested wheelis large in size, large in load, high in speed and constant in traction force; and the test result is more accurate. The manned lunar rover wheel soil bin test bed is convenient to operate, safe and reliable, the wheel performance under different conditions is tested by changing the load, the rotating speed, the traction resistance and the like of the tested wheel, the effect of multiple test conditions can be achieved, the test diversity can be improved, data such as the test rotating speed, the test time and the power can be output at any time through the sensor and the computer, and recording is convenient.

Description

technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to a soil tank test bench for a wheel of a manned lunar vehicle. Background technique [0002] In recent years, with the increase of people's interest in lunar exploration, the development of manned lunar vehicles has been paid more and more attention. Since the surface of the moon is covered with a thick layer of lunar soil, and the gravity is only 1 / 6 of that of the earth, the manned lunar vehicle is easy to sink and slip. Therefore, the mobility of manned lunar vehicle wheels has received extensive attention and research. Optimizing the wheel structure of the manned lunar rover, evaluating and predicting the wheel performance of the manned lunar rover are of great significance for ensuring the work of the manned lunar rover and lunar exploration. Using the soil tank test bench to measure the basic data and evaluate the passability, traction and reliability of the...

AI Technical Summary

Problems solved by technology

[0003] The existing soil tank test bench is mainly aimed at small unmanned lunar rover wheels. The tested wheels are small in size, small in load, low in running speed, and unstable in traction resistance, which cannot meet the test requirements of large manned lunar rover wheels.
