Centrifugal deployments have a possibility of unfolding large membranes without using extendable masts. Understanding and predicting the deployment dynamics are important to realize large membrane space structures. In this paper, deployment experiments of hexagonal membranes with coarse and fine spiral folding patterns are conducted in vacuum under gravity. Numerical simulations of the centrifugal deployments are also performed employing spring-mass system which models in-plane stiffness of thin membranes and enables fast numerical analysis. Modelings of buckling, creases, air drag and damping are added to the spring-mass system model and initial shapes are adjusted to experimental models. The experimental and numerical results are compared to examine the characteristics of the deployment dynamics and the validity of the numerical.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_5_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064734065","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究本部"},{"subitem_text_value":"東京大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"奥泉, 信克"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"山本, 貴也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okuizumi, Nobukatsu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamamoto, Takaya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Experiments and Simulations of Centrifugal Deployments of Membranes Stowed with Spiral Folding","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Experiments and Simulations of Centrifugal Deployments of Membranes Stowed with Spiral Folding","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1554","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7370","relation_version_is_last":true,"title":["Experiments and Simulations of Centrifugal Deployments of Membranes Stowed with Spiral Folding"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:40:33.977554+00:00"}
