Abstract
Tensegrity structure has advantages of light weight, simple shape of the members and easy building etc. In the paper, a cylindrical tensegrity structure is presented and researched. At first, based on a cylindrical origami structure, the method of arranging the bars and strings of the cylindrical tensegrity structure is presented. Then the connectivity matrix is set up. The mathematical model is set up further. Length of the members is obtained further and a model of the cylindrical tensegrity structure is built. The model proves the stability of the structure and feasibility of designing it. The force equilibrium equation of the structure is obtained further. Optimization method is applied to get the minimal mass and section sizes of the members. Through researching in the paper, the method for designing a kind of new tensegrity structure is obtained and configuration of the tensegrity structure is enriched.
