| Research Abstract |
A new design methodology for light-weight, huge-scale antenna reflector structures is investigated. The reflector structure consists of a metal mesh surface, a cable network structure(a system of cables) and a deployable frame stricture. The cable rigidity and the surface edge shape, were considered in this design. A homologous design method was applied to design the supporting structure. As a result, the weight of the supporting structure can be effectively reduced. In addition, by constructing hierarchical module structures, the modular structures can show a self-similarity. We are expecting to obtain structural characteristics of a whole huge structure by testing a few basic modules.
