Quasi-regular ten-angular prism tensegrity deployable mechanism
The invention aims to provide a quasi-regular ten-angular prism tensegrity deployable mechanism. The quasi-regular ten-angular prism tensegrity deployable mechanism is formed by twenty nodes, two pulling cables, ten springs and ten pressing rods, wherein the two pulling cables are respectively positioned on twenty vertexes of a similar-regular ten-angular prism of which the bottom surface and the top surface are oppositely twisted by 30 degrees; each pulling cable penetrates through a sleeve ring arranged at the section part of a surface where each pulling cable is located; the ten springs are coincided with ten vertical edges of a twisted regular six-prism frustum; the ten pressing rods are positioned in the similar ten-angular prism; each pressing rod is respectively connected with one bottom surface node and a top surface node; each node is connected with one pulling cable, one spring and one pressing rod; the pulling cables and the springs have pre-tension forces; the pressing rods have pre-compression forces; the pre-tension forces of the pulling cables and the springs and the pre-compression forces of the pressing rods are in mutual balance. According to the quasi-regular ten-angular prism tensegrity deployable mechanism disclosed by the invention, the problems of the prior art that the folding volume is large and the unfolding reliability is low can be solved; the quasi-regular ten-angular prism tensegrity deployable mechanism is large in deployable space, light in weight and small in folding volume.
