An advanced design method has been developed for manufacturing large fiber-reinforced-plastic (FRP) structures to be used in next-generation satellites such as the quasi-zenith satellite (QZS). The design method enables highly accurate shape and strength predictions, including of the thermal residual stresses, without trial manufacture. The design, manufacture and tests of the satellite's main structure (verification model) are also reported. The verification model is used to make the main structure of the successfully launched QZS.

When a satellite separates from the rocket in space, large shocks occur in the satellite's body structure. To evaluate * 原稿受付 2011 年 6 月 13 日 *1 正員,三菱電機 (株) 先端技術総合研究所(〒661-8661 兵庫県尼崎市塚口本町 8-1-1) *2 三菱電機 (株) 鎌倉製作所 *3 正員, (独) 宇宙航空研究開発機構
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
