A heart-shaped tensegrity structure

Abstract

The invention provides a heart-shaped stretch-draw integral structure, and belongs to the technical field of stretch-draw integral structure design. The structure is composed of 46 joints, 87 cable units and 44 rod units, and comprises four parts of P1, P2, P3, P4, wherein the number of the first parts P1 is 5, the number of each of the second parts P2 and the third parts P3 is 2, the number of the fourth parts P4 is 1, the first parts, the second parts and the third parts are all of quadrangular or quadrangular stretch-draw integral structures, and each is composed of 8 joints, 12 cable unitsand 4 rod units. The fourth part is of a deformation structure of the quadrangular stretch-draw integral structure. All joints are ball hinges, and the rod units and the cable units can rotate at thejoints. The appearance of the heart-shaped stretch-draw integral structure is similar to a heart, and the heart-shaped stretch-draw integral structure has the characteristics of being rich in impliedmeaning, easy to build up, attractive in appearance and the like, and can serve as artistic sculptures and other decorative structures.

Description

technical field [0001] The invention relates to the technical field of tension integral structure design, in particular to a heart-shaped tension integral structure. Background technique [0002] The tensegrity structure is a light-weight, beautiful, large-span, high-material-utilization, grid-like space structure system, which is composed of cable units bearing tension and rod units bearing pressure. In the case of no external load, it can maintain its own geometric configuration by relying on the prestressing effect of rods and cables. The structural stiffness is positively correlated with the prestress level of the structure. Once a certain unit loses the prestress or fails, the structure will undergo large deformation or even fail. The structure has the ability of self-adaptive self-balancing. Under the condition of bearing a certain external load, it can restore itself to a self-balancing state by adjusting the unit length and node displacement. [0003] Structural de...

Problems solved by technology

Therefore, the shape of the tensegrity structure has certain particularity, and the geometric shape cannot be arbitrarily constructed according to personal wishes.

[0004] The heart-shaped structure is a structure with beautiful appearance and rich meaning, but in the field of tensegrity, no one has used this structure as a prototype to design structures to enrich the tensegrity structure
