Abstract

In this paper, the structure of a large spaceborn deployable antenna is optimized in condition with its working state. The main aim is to obtain the lightest antenna's weight for lower costs. In the optimization process, the optimum mathematic model is established with outer radius of antenna's beam elements and cable tensions as variables, surface precision and natural frequency as constrains, and antenna's weight as objective. Based on the finite element analysis, a genetic algorithm is used to solve this nonlinear mathematic model. And results of example show that this optimization method can effectively reduce antenna's weight as well as keep antenna's structural properties satisfied.
