A bionic walking wheel with low dust and high traction on the lunar surface

Abstract

A bionic walking wheel with low dust and high traction on the lunar surface belongs to the technical field of engineering bionics. The present invention is composed of a wheel hub, a tire assembly and a wheel thorn group by imitating the surface shape of the sole of an ostrich, the contour of a toenail and the motion characteristics of the third toe. , mainly used in manned fast lunar rover. During the rolling process of the bionic walking wheel, the protruding length of the wheel thorns can be adjusted adaptively according to the load on the wheel and the condition of the lunar surface, so as to improve the traction and passability of the bionic walking wheel. When the tire surface is in contact with the lunar surface, its surface structure fixes the lunar soil under the wheel, reducing the disturbance of the wheel to the lunar soil. Through simulation analysis, it is found that the bionic walking wheel with low dust and high traction on the lunar surface of the present invention increases the traction force of the hook by about 90% compared with the screen wheel, and reduces the amount of dust by about 51%, and has a simple structure, light weight, no inflatable, The traction performance and dust suppression effect are good, which helps to improve the adhesion, traction and dust suppression of the manned fast lunar rover.

Description

technical field [0001] The invention belongs to the technical field of engineering bionics, in particular to a bionic walking wheel with low dust and high traction on the lunar surface imitating the curved surface of the sole of an ostrich foot, toenails and motion characteristics. Background technique [0002] The lunar surface contains many resources that humans need. With the extraction of global resources and the shortage of energy, people began to turn their attention to other planets in space. Deep space exploration has become an inevitable trend in future development, and deep space exploration technology also affects a country's comprehensive national strength and status. At present, many countries in the world have successfully completed deep space exploration missions. However, because the lunar surface is dominated by loose sandy soil, some deep space probes have poor passability on soft ground and low wheel traction, resulting in wheel subsidence and Slips and ...
