Abstract

A ball rod truss unit based on memory alloy relates to the technical field of space truss structure. The invention solves the problems of low connection efficiency and high transportation cost of theprior space truss structure. The four connecting spheres are rectangular in distribution, wherein one connecting rod is arranged between two connecting spheres which are diagonally distributed and oneconnecting rod is arranged between two adjacent connecting spheres, the end of each connecting rod and the connecting sphere are fixedly connected by a memory alloy card, the first elastic tenon is fixedly connected with the connecting rod through a connecting section, one end of the first elastic tenon is provided with a plurality of barb structures distributed in a ring shape, the first elastictenon is clamped in a through hole of the connecting sphere, and a barb fitting hook of the first elastic tenon is arranged in the clamping groove, the connecting section is of a tubular structure, the inner wall of the connecting section is pasted with a first electric heat conductive fin along the circumferential direction thereof, there is no gap contact between the connecting section and theconnecting sphere, and an end part of the connecting section far away from the connecting sphere is inserted in the connecting rod and is fixedly connected with the connecting rod through a colloid. The barb fitting hook of the first elastic tenon is arranged in the clamping groove.

Description

technical field [0001] The invention relates to a ball bar truss unit based on a memory alloy and belongs to the technical field of space truss structures. Background technique [0002] The on-orbit lap truss and the direction expansion of the truss are used for astronauts to work in space and connect other space structures on the truss. In the prior art, the manufacturing technology of the space truss structure is manufactured on the ground, and unfolded in space after being folded up and launched. The size of the large space truss structure is limited by the space of the launch vehicle. In order to reach a length of hundreds or even thousands of meters, a very high expansion ratio is required, the design is difficult, and the transportation cost is high. Moreover, the connection methods between the various parts in the prior art are generally threaded connections or flexible wire rope connections, so most of them need to install the connecting rods on the ground in advanc...
