Low-flying-dust high-traction bionic walking wheel on lunar surface

Abstract

A low-flying-dust high-traction bionic walking wheel on a lunar surface belongs to the technical field of engineering bionics, is formed by simulating the curved surface morphology of the sole of an ostrich, the contour of a toenail and the motion characteristics of the third toe, is composed of a hub, a tire assembly and a wheel thorn group, and is mainly applied to a manned rapid lunar rover. In the rolling process of a bionic walking wheel, the extending length of the wheel thorns can be adjusted in a self-adaptive mode according to the load on the wheel and the lunar surface condition, and the traction force and passing ability of the bionic walking wheel are improved. In the contact process of a tire tread and the lunar surface, the surface structure of the tire tread fixes lunar soil under the wheel, and the disturbance of the wheel to the lunar soil is reduced. Simulation analysis shows that compared with a screen wheel, the low-flying-dust and high-traction bionic walking wheel for the moon surface has the advantages that the hook traction force is increased by about 90%, the flying dust amount is reduced by about 51%, and the low-flying-dust and high-traction bionic walking wheel is simple in structure, light in weight, free of inflation and good in traction performance and flying dust suppression effect; and the adhesiveness, the traction property and the dust suppression property of the manned lunar rover can be improved.

Description

technical field [0001] The invention belongs to the technical field of engineering bionics, and in particular relates to a bionic walking wheel with low dust emission and high traction on the lunar surface imitating the curved surface of ostrich soles, toenails and movement characteristics. Background technique [0002] There are many resources needed by human beings on the surface of the moon. With the exploitation 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 of future development, and deep space exploration technology also affects a country's overall national strength and status. At present, many countries in the world have successfully completed deep-space exploration missions. However, since the surface of the moon is dominated by loose sandy soil, some deep-space probes have poor passability on soft ground and low traction on the wheels, resulting in...
