Tensegrity structure unit based on truncated tetrahedron geometry
The present invention discloses a tensegrity structure unit based on the truncated tetrahedron geometry. The unit is composed of twelve hinged joints, twelve internal pressing bars and eighteen peripheral guys, wherein the twelve hinged joints are disposed on twelve vertexes of a truncated tetrahedron; two ends of each pressing bar are connected with a node of the surface of a triangle surface of the truncated tetrahedron and a joint, farest away from the node, in a hexagon surface parallel with the triangle surface respectively; and two ends of the eighteen pull cables are connected with the vertexes of the truncated tetrahedron, thus to form a peripheral outline the truncated tetrahedron. All the joints are hinged joints, and two pressing bars and three pull cables are connected at each joint. A pre-tension force exists in all the pull cables while a pre-compression exists in all the pressing bars, and the structure unit is a stable self-balancing cable-bar structure system, has an excellent structural stiffness, and has a good application prospect in a big complicated pre-stressed cable-bar structure system.
