A manned lunar rover wheel with high bearing performance, high vibration buffering performance and high traction performance comprises a bionic wheel face and a bionic hub structure, the bionic wheel face is of an integral structure formed by nine sections of wheel face single body arrays, the cross section curve of each wheel face single body is a bionic curve obtained by optimizing an ostrich sole contour line, and the wheel face structure is beneficial to sand stabilization and current limiting; the traction performance of the wheel is improved. A bionic wheel face monomer boss is fixedly connected with a bionic hub, eight rows of convex body structures are arranged on the surface of the bionic wheel face monomer boss, each row of convex body structures are distributed along a bionic curve obtained by optimizing an ostrich plantar mastoid arrangement rule, and the effects of improving attachment and increasing traction are achieved. A square hole is formed in a single groove of the wheel surface, is of a screen structure and has the effects of stabilizing sand, limiting flow and increasing traction; the outer contour curve of the axial section of the bionic hub is a bionic curve obtained by optimizing the body contour line of the ironbeetle, and the effect of improving the bearing performance is achieved; the contour lines of the bionic through holes in the two sides of the bionic hub are bionic curves obtained by optimizing the contour lines of cells in the mammalian foot pad, and the effect of improving the vibration buffering performance is achieved.
Description
technical field [0001] The invention belongs to the technical field of engineering bionics, and relates to a wheel of a manned lunar rover with high load bearing, high vibration damping and high traction performance. Background technique [0002] The surface of the moon contains a large number of resources, such as nuclear fusion materials - helium 3, rare earth elements and ilmenite and so on. As the global energy strategy gradually turns its attention to lunar exploration, the development of manned lunar mobile vehicles and lunar mobile test bases has become a top priority. Wheels are an important part of manned lunar mobile vehicles and lunar mobile test bases, and are crucial to improving the high-pass performance of lunar mobile devices. Manned lunar mobile vehicles and lunar mobile test bases require wheels to have excellent load-bearing and shock-absorbing properties. However, the load-bearing performance of the existing manned lunar rover wheels is not enough, and ...
