Problems solved by technology

In the working environment of loose sandy soil, due to the poor bearing capacity and shear strength of the sandy soil, the traction performance of ordinary wheels is very unsatisfactory
When a wheeled vehicle equipped with ordinary smooth-tread wheels is driving on sandy ground, the vehicle’s passing performance is seriously affected due to wheel slippage and subsidence, which limits the exploration and exploitation of mineral resources and energy in loose sandy soil working environments

Embodiment Construction

[0022] see figure 1 , figure 2 , image 3 and Figure 4 As shown, in the present invention, several identical wheel surface structures 2 are formed on the surface of the reference wheel 1, and the wheel surface structure 2 is formed by stretching along the width of the wheel 1 with a curved section 3 smoothly overlapped by seven circular arc sections. , based on the scale of the reference wheel 1, the relevant scale data of the seven arc segments are as follows; the unit of length is mm: as figure 1 shown;

[0023] Reference wheel: O=(0,0), R=150; O is the center of the circle, R is the radius;

[0024] The first arc segment: O 1 =(0,-159.2),R 1 =9.2, θ 1 =47.473°; O 1 is the center of the first arc segment, R 1 is the radius of the first arc segment, θ 1 is the included angle of the first arc segment;

[0025] The second arc segment: O 2 =(-21.372,-139.598), R 2 =19.8, θ 2 =101.65°; O 2 is the center of the second arc segment, R 2 is the radius of the second...

Abstract

The invention discloses a high-trafficability simulated sand crossing wheel face structure which is characterized in that a plurality of wheel face structures are formed on the surface of a reference wheel, and each wheel face structure is formed that a curved section composed of seven arc segments which are smoothly overlapped stretches along the width of a wheel. Compared with the sand crossing wheel in a smooth wheel face structure with the same size, the sand crossing wheel in the high-trafficability simulated sand crossing wheel face structure provided by the invention has the advantages that the tractive force of a hook is improved by 3.2 to 6.5 percent, the traction efficiency is increased by 3.9 to 7.1 percent, in the invention, the sandy soil stress field distribution range under wheel is effectively increased, and the effect of the wheel face to sandy soil can be enhanced; in addition, the relative flow velocity of sandy soil under the wheel face is reduced. Compared with a smooth wheel face, the simulated sand crossing wheel face has the advantage that the lateral sand soil flowing speed under the simulated sand crossing wheel face is lowered by 11.1 to 13.7 percent, and the superior sand stabilizing and flow restricting effect of the simulated sand crossing wheel face can be embodied.

Description

technical field [0001] The invention relates to an engineering bionic structure, in particular to a bionic sand-surfing wheel surface structure with high passability. The invention improves the traction passability of vehicles when running in soft medium environments such as deserts, Gobi, the moon, and Mars. In the present invention, by studying the surface shape of the sand-touching part of the ostrich's sole during the process of ostrich crossing the sand, according to the principle of engineering bionics, based on the interaction between the surface of the sand-crossing wheel and the sand and soil, and through parameter optimization, a bionic sand-crossing wheel with high passability is invented. surface structure. Background technique [0002] With the advancement of science and technology and social development, people's demand for resources, especially energy, has been increasing, and resource reserves in conventional areas have become increasingly scarce. People have...
