Problems solved by technology

[0005] Peripheral truss deployable antennas have good performance advantages in the field of large-aperture and super-large-aperture deployable antennas. Relevant researchers from various countries have done a lot of research on the deployment mechanism, cable net forming and deployment control of peripheral truss deployable antennas. But on the whole, there are still few types of deployable antenna mechanisms with peripheral trusses currently in orbit, and with the increase of the antenna aperture, the overall structural rigidity drops more seriously

Abstract

The invention relates to a peripheral truss deployable antenna mechanism based on V-shaped shear type unit bodies. The peripheral truss deployable antenna mechanism comprises N V-shaped shear type unit bodies, wherein each V-shaped shear type unit body is formed by rotatably connecting four internal disc chucks, four external disc chucks, two intermediate disc chuck, an internal shear type connecting rod, two folding rods, two intermediate shear type connecting rods and two external shear type connecting rods; the N V-shaped shear type unit bodies are arranged in an array, the two adjacent V-shaped shear type unit bodies are connected with each other through sharing two internal disc chucks, two external disc chucks and one intermediate shear type connecting rod, and the N V-shaped shear type unit bodies form a closed deployable antenna mechanism. The overall mechanism has high structural symmetry, can form the peripheral truss deployable antenna mechanisms of different scales throughchanging the number of the V-shaped shear type unit bodies in the overall mechanism and the length of the rod members in the V-shaped shear type unit bodies, and can be applied to large-diameter satellite-borne antennas.

Description

technical field [0001] The invention belongs to the technical field of antenna mechanisms, and in particular relates to a peripheral truss expandable antenna mechanism based on a V-shaped scissor unit body. Background technique [0002] With the continuous advancement of space science and technology, various space missions are gradually becoming diversified and complex. Satellites are an important tool for space exploration and ground communication. An important load for transmission, its performance is directly related to the overall completion of satellite missions. Relevant researchers have conducted a lot of research on spaceborne antennas, and it has gradually become one of the research hotspots in the aerospace field. [0003] Restricted by the limitation of the effective space of the launch vehicle, space-borne antennas are usually launched, carried and folded, and deployed in orbit to realize their functions. The deployment and retraction rely on the space expandable...
