Embodiment Construction

[0026] see Figure 5 , Figure 7 As shown in Figure 8, the outer contour of the section of the bionic wheel spine 2 of the lunar rover wheel 1 is the typical three closed edge characteristic curves of the imitation 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 for obtaining the three closed curves of the outer contour of the section of the bionic wheel thorn 2 of the lunar rover wheel 1 is:

[0031] (1) Point cloud data acquisition:

[0032] The sample used in the present invention comes from an adult ostrich in Lushengyuan Villa, Changchun. The ostrich has unique toes, which determine its anti-sinking and anti-sliding ability in sandy terrain. Pick typical ostrich toenails, such as figure 1 As shown, the developer is sprayed on the surface of the ostrich toenail, an...

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 bionic wheel thorn of a lunar vehicle wheel, which is applied to the interdisciplinary field of lunar exploration engineering. In the present invention, the toenail, the main sand-touching part of the steady and high-speed running ostrich in the desert, is used as the bionic prototype. According to the theory of engineering bionics, reverse engineering technology is adopted to complete a bionic wheel thorn design of the lunar rover wheel. Background technique [0002] The recent planning of my country's lunar exploration aims at unmanned lunar exploration, and has determined the strategic goal of "three steps": the first step is to explore around the moon, and the second step is to detect the soft lander on the lunar surface and the lunar rover. Surface inspection and survey; the third step is the automatic sampling and return of ...
