Embodiment Construction

[0026] See Figure 5 , Figure 7 As shown in Figure 8, the outer contour line of the cross-section of the lunar rover wheel 1 bionic spur 2 is the typical three closed edge characteristic curves of imitating ostrich toenail, and the three closed curves conform to the following formula:

[0027] Curve 1: y=-0.0058x 3 -0.0356x 2 -0.2583x-0.0636;

[0028] Curve 2: y=-0.06x 2 -0.4709x+4.5046;

[0029] Curve 3: y=0.047x 2 +0.2526x+4.9872.

[0030] The method of obtaining the three closed curves of the outer contour of the lunar rover wheel 1 bionic thorn 2 section is:

[0031] (1) Point cloud data acquisition:

[0032] The sample used in the present invention comes from the adult ostrich of Changchun Lushengyuan Mountain Villa. The ostrich has unique toes, which determines its anti-sagging and anti-slip ability during sand operation. Pick a typical ostrich toenail, such as figure 1 As shown, the surface of the ostrich toenail is sprayed with a developer, and the non-contact laser measuremen...

Abstract

The invention discloses a bionic wheel lug for a lunar vehicle wheel. The outer contour line of the section of the bionic wheel lug for the lunar vehicle wheel is three typical ostrich toe nail imitated closed edge feature curves; the formula of a curve 1 is that y is equal to -0.0058x<3>-0.0356x<2>-0.2583x-0.0636; the formula of a curve 2 is that y is equal to -0.06x<2>-0.4709x+4.5046; the formula of a curve 3 is that y is equal to 0.047x<2>+0.2526x+4.9872; and the bionic wheel lug can effectively improve the trafficability of a lunar vehicle on soft lunar soil, obviously improve the traction performance and the sinking resistance of the lunar vehicle wheel travelling on the soft lunar soil, improve the travelling efficiency of the lunar vehicle, reduce the travelling hidden danger and hazard of the lunar vehicle on the lunar surface, and provide important theoretical and technical basis for smooth implementation of touring and investigation of an unmanned lunar vehicle and lunar surface travelling of a manned lunar vehicle in a lunar exploration program in China.

Description

Technical field [0001] The invention belongs to the field of combining engineering bionics and ground vehicle mechanics. The invention relates to a lunar rover wheel bionic spur, which is applied to the interdisciplinary field of lunar exploration engineering. In the present invention, the toenail, the main sand-touching part of the stable and high-speed running ostrich in the desert, is used as the bionic prototype. According to the engineering bionics theory, reverse engineering technology is adopted to complete a lunar rover wheel bionic spur design. Background technique [0002] my country’s recent plan for lunar exploration is aimed at unmanned lunar exploration, and has determined the "three-step" strategic goal: the first step is to detect around the moon, and the second step is to detect the position of the lunar soft lander and the lunar rover. Surface inspection and survey; the third step is the automatic sampling and return of the lunar surface. With the smooth complet...
