Mesh surface installation method of rib mesh type deployable antenna

Abstract

The invention relates to a mesh surface installation method of a rib mesh type deployable antenna. The mesh surface mounting method comprises the following steps: (1-1) placing other antenna structures except a mesh surface on a horizontal working plane; (1-2) arranging a lateral limiting support on the working plane, and restraining lateral movement of each rib; (2-1) flatly paving the cut net surface above the ribs; (2-2) temporarily fixing the inner end and the outer end of each rib in the length direction and the corresponding position of the net surface; (2-3) uniformly pressing the mesh surface downwards until the mesh surface is smoothly attached to the upper edge of the rib, and temporarily fixing the overlapping line part of the upper edge of the rib and the mesh surface; (3-1) sewing the ribs and the mesh surface along the upper edges of the ribs by adopting sewing threads, and gradually removing temporary fixation; (3-2)enabling the mesh surface to be subjected to edge locking, and cutting off the cutting allowance on the periphery of the mesh surface; and (3-3) removing all the lateral limiting supports, and completing the process. The invention provides an efficient and simple net surface mounting method for the rib net type deployable antenna, the applicability is high, and a standard process can be formed.

Description

technical field [0001] The invention belongs to the technical field of aerospace structures, and relates to a method for installing a mesh surface of a rib mesh type deployable antenna. Background technique [0002] In recent years, the aerospace field has developed rapidly, and the number of spaceborne antennas launched into orbit has increased year by year or even exploded. Among them, the rib-mesh deployable antenna that meets the requirements of reliability, storage ratio, precision and light weight has been widely developed and applied. [0003] In the rib-mesh deployable antenna, according to the movement form of the rib during the deployment process, it is divided into an umbrella-shaped folded rib form and a helical winding rib form. The rib-mesh antennas that have been launched into orbit cover the caliber of 1m to 10m, and have high practical value and application prospects. [0004] However, at present, most of the spaceborne antennas that have achieved industri...
