Abstract
It is necessary to develop satellite with large diameter reflectors to offer high communication services, or to obtain image pictures with high resolution for radio astronomy. The purpose of this study is establishment of cable network structure integrated with compression members for 10m class deployable precise and large antenna reflectors. The cable network is a key theory to make prerace parabola surface. In this study, we propose design method for cable network structure integrated with compression members. In the design process of the cable network systems, many parameters and conditions are required to be determined such as extension rigidity of cable and compression member, cable network topologies and tie cable tensions. We suggested the new design method that introduced cable adjustment. As the result of this study, we showed the design guidelines of reduction deformation of supporting structure and reflection area loss using numerical analysis. And, it is possible to reduce the deformation of the support structure. Even when many number of facets, proposed the design method inclusive cable network compression member maintain tension balance.
