Deployment Design of the Parabolic Solid Reflector Antenna Structure

Abstract

According to the actual requirements of limitation on the number of blocks and envelope size of solid reflector deployable antenna structure, the block optimization and connection design of parabolic rigid deployable antenna structure are conducted. The single-vertex five creases origami pattern with two degrees of freedom is selected for block optimization based on the mobility analysis, but one crease is limited to rotate in order to ensure that the motion path of the reflector can be controlled effectively. A plane unit circle model is used to qualitatively analyze the influence of geometric parameters on the storage ratio of reflector mechanism. The optimization framework of parabolic rigid deployable antenna structure is established by taking the storage ratio as the objective function and taking the rigid constraints, collision constraints and mobility constraints as the optimization constraints. The design parameters of panels are calculated by 1stOpt combined with the simplex method and general global optimization algorithm (SM-GO). Connections and rotating shafts are designed to solve the collision problem in the process of panel rotation. Simulation analysis and 3D print blocks model are given to demonstrate the feasibility and rationality of the method.
