OPTIMIZATION ON INITIAL CABLE TENSIONS AND NUMBER OF CABLES FOR A CABLENET DEPLOYABLE SPACEBORNE ANTENNA

Abstract

Abstract: Optimization on initial design of a cable-net antenna is made according to the special requirements for space-borne antenna. Optimal mathematical model is built with goals of minimum vertical cable number and surface accuracy, design variables of numbers of vertical cables and cable tensions, and constraints of stresses and basic frequency. Since it is difficult for traditional optimization methods to solve such a problem with mixed variables, biobjective and strong nonlinearity, a genetic algorithm is used instead. The optimal result shows the validity and effectiveness of the proposed method and model.

Key words: Genetic algorithm, Cable-net deployable space-borne antenna, Surface accuracy
