Stretching and drawing integral structure in shape similar to frustum of regular hexagonal prism

Abstract

The invention discloses a stretching and drawing integral structure in a shape similar to a frustum of a regular hexagonal prism. At present, no stretching and drawing integral structure in the shape of the frustum of the regular hexagonal prism or the shape similar to the frustum of the regular hexagonal prism exists. The stretching and drawing integral structure in the shape similar to the frustum of the regular hexagonal prism is formed by twelve joints, twenty-four inhaul cables and six pressure bars totally, wherein the twenty-four inhaul cables can be further subdivided into four sets, and each set has six inhaul cables. The twelve joints are located on twelve top points of the bottom face and the top face of the similar frustum of the regular hexagonal prism, and the bottom face and the top face are twisted one degree relatively. All the inhaul cables are arranged on the surfaces of the frustum of the regular hexagonal prism. The first set of inhaul cables are arranged on the bottom face and coincide with six edges of the orthohexagonal bottom face. The second set of inhaul cables are arranged on the top face and intersect with one another to form a regular hexangular star shape. The third set of inhaul cables coincide with six vertical edges of the twisted frustum of the regular hexagonal prism. The fourth set of inhaul cables are located on diagonal lines of six side faces of the twisted frustum of the regular hexagonal prism. The six pressure bars are located inside the prism. Each pressure bar is connected with one joint of the bottom face and one joint of the top face. All the joints are hinged joints. Each joint is connected with four inhaul cables and one pressure bar. All the inhaul cables have pretension force. All the pressure bars have pre-pressure force. The pretension force of the inhaul cables and the pre-pressure force of the pressure bars are mutually balanced.

Description

technical field [0001] The invention relates to a tensioned integral structure, in particular to a tensioned integral structure with a regular hexagonal truss shape and 6 compression rods and 24 stay cables. Background technique [0002] The tensegrity structure is a prestressed self-balancing system composed of compression rods and tension cables. The stiffness of this type of structure is provided by prestress, and the internal forces of the components are self-balanced. Once the prestress is lost, the structure will not be stable. re-established. The tensegrity structure has the advantages of light weight, large span, and beautiful shape, and has attracted extensive attention from academic and engineering circles. [0003] Since the tensegrity structure is a prestressed self-balancing system, the connection relationship between its node position and components must meet the prestressed self-balancing conditions, and the geometric shape cannot be arbitrarily constructed l...

Problems solved by technology

Although some tensegrity structures are designed based on a specific type of geometry, their final shape deviates from the original standard geometry

At present, there is no tensegrity structure with the shape of prism or near prism.
