Layout optimization of mesh antenna with multi-objectives based on dynamics

摘要

To ensure the electromagnetic performance of the space antenna and compromise the weight, surface error, and the arrangement of cables, the paper presents the optimization method for the cable mesh deployable antenna design. Optimal mathematical model is built with minimum weight and surface error as objectives, number of vertical cables and radiant units, and cable forces as design variables, and stresses and fundamental frequency as constraints. A genetic algorithm is taken for solving. The optimal results show the validity and effectiveness of the proposed method and model.
