Problems solved by technology

[0004] Due to the good performance advantages of the perimeter truss deployable antenna 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 the perimeter truss deployable antenna. However, 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 discloses a cell array type single-degree-of-freedom peripheral truss expandable antenna mechanism which comprises N outer-layer single-degree-of-freedom expandable mechanism units and Ninner-layer single-degree-of-freedom expandable mechanism units, the outer-layer single-degree-of-freedom expandable mechanism units are formed by connecting inner joint connecting members, inner connecting rods, intermediate connecting rods, outer connecting rods and outer joint connecting members through rotating pairs, and the two types of single-degree-of-freedom expandable mechanism units are interspersed and arranged in an array and are connected by sharing two intermediate connecting rods, two inner joint connecting members and two outer joint connecting members to form a multi-facetedperipheral truss mechanism. The overall mechanism has a high structural symmetry, the peripheral truss expandable antenna mechanisms of different scales can be formed by changing the numbers of the inner-layer and outer-layer single-degree-of-freedom expandable mechanism units in the overall mechanism and the lengths of the rods inside, and the peripheral truss expandable antenna mechanism can beapplied to a large-caliber satellite-borne antenna well.

Description

technical field [0001] The invention relates to a deployable antenna mechanism, in particular to a unit array type single-degree-of-freedom peripheral truss deployable antenna mechanism. Background technique [0002] With the continuous development of space science and technology, the amount of information collected and transmitted by space satellites, space stations and other spacecraft continues to increase, and the role of antennas as information transmission and receiving devices in the process of space communication and data transmission is becoming more and more prominent. In order to increase the amount of information transmitted in space, it is necessary to continuously increase the transmission bandwidth and signal gain. The most direct and effective method is to increase the aperture of the space antenna, which can simplify the ground receiving device while increasing the amount of information transmitted in space. Due to the limitation of the volume of the rocket ...
