Abstract

The invention discloses a framework-type antenna cable net electromechanical integration manufacturing method which is based on the particle swarm optimization. A tension balance condition and the upper and lower limits of cable segment tension are used to form a fitness function. An optimization algorithm is utilized to solve a cable net structural mechanical model to search for a sag structure at the boundary of the module cable net. According to the invention, through construction of the appropriate fitness function, a constraint problem is transformed into an unconstrained problem so as to select the PSO algorithm to carry out solving. The manufacturing method of the invention can design the cable net mechanical structure of an antenna to guarantee the mechanical properties of the cable net within a permission range, thereby greatly reducing influences on electrical properties of the antenna by slits in a plane of reflection.

Description

technical field [0001] The invention belongs to the technical field of framed antennas, in particular to an electromechanical integrated manufacturing method of a framed antenna wire net. Background technique [0002] The frame-type deployable antenna is composed of multiple space units and is a mesh reflector antenna; its unique modular design concept can effectively meet the large-aperture and high-precision requirements of the antenna structure. The frame-type extendable antenna is composed of an upper metal cable net and a lower back frame. In the early stage of the overall assembly of the antenna, the modules are designed and debugged separately, and the nodes on the cable network boundary of the modules must be indented inward under the condition of cable tension balance to form a vertical span structure. The existence of the vertical-span ratio makes the area of ​​the cable-net triangle surface at the boundary defective, resulting in gaps between the modules on the r...
