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: Cable-net deployable space-borne antenna Surface
