Tensegrity structure similar to truncated tetrahedron
The invention aims at providing a tensegrity structure similar to a truncated tetrahedron. The shape of the tensegrity structure is obtained by cutting small regular tetrahedrons from four corners of a regular tetrahedron, wherein the edge length of the small regular tetrahedrons accounts for 1/3 of the existing edge length. The tensegrity structure is composed of 12 joints, 18 inhaul cables and 6 pressing rods. The 12 joints are located at vertexes of the truncated tetrahedron and distributed on a spherical face, namely, a circumscribed sphere of the truncated tetrahedron, wherein the radius of the circumscribed sphere is 1.1726 times of the cable length. The 18 inhaul cables are distributed on the edges of the truncated tetrahedron, and the 6 pressing rods are located in the truncated tetrahedron. Each joint is connected with the three corresponding inhaul cables and the corresponding pressing rod. All the inhaul cables are equal in length, and all the pressing rods are equal in length. All the joints are hinge points, all the inhaul cables have pretension force, and all the pressing rods have precompression force. The pretension force of the inhaul cables and the precompression force of the pressing rods are balanced. The tensegrity structure is larger in bearing capacity, can bear stuff in multiple directions and can achieve more functions.
