Quasi-cuboctahedron tensegrity structure
The invention aims to provide a quasi-cuboctahedron tensegrity structure. The shape of the quasi-cuboctahedron tensegrity structure is obtained by connecting midpoints of every two adjacent edges and removing eight corners on the basis of a cube. The quasi-cuboctahedron tensegrity structure is formed by twelve nodes, twenty-four pulling cables and twelve pressing rods, wherein the twelve nodes are respectively positioned on vertexes of a cuboctahedron and are distributed on one spherical surface, i.e., a circumscribed sphere of the cuboctahedron; the radius of the circumscribed sphere is equal to the length of each pulling cable, namely, the side length; four equilateral triangles are formed by distributing the twenty-four pulling cables on edges of the cuboctahedron and the twelve pressing rods in the cuboctahedron and are nested to one another. The quasi-cuboctahedron tensegrity structure provided by the invention has the characteristics of a regular tetrahedron and a regular hexahedron and is symmetrical and attractive in structure; compared with a first-order tensegrity structure, rods of a second-order tensegrity structure are in contact with each other, the rigidity is larger, and the requirement on larger rigidity can be met; compared with the first-order tensegrity structure, the bearing capacity is also larger.
