圧縮部材を含むケーブルネットワークアンテナの基礎的鏡面成形法

抄録

In order to offer new mobile communication services, or to obtain high-resolution image picture for radio astronomy, it is necessary to develop satellite with large aperture reflectors and high accuracy. While at the same time weight must be reduced within the weight budget determined from the system requirements. Conventional study has been proposed a new surface forming concept in which the cable network is assembled by tensile and compression members. As a result, the effectiveness of the proposed method for reducing the weight of the antenna structure has been analytically shown. However, we must verify based on an experiment by using a cable network model and examine the application possibility of this method. Therefore, this paper describes manufacture a prototype model based on design analysis for the proposed weight reduction method and verify based on an experiment the effectiveness of the compression members.
