In order to land on any surface we want to explore, we need some sort of landing gear which attenuates touchdown impulsive force and turnover moment of the lander. However, conventional landing gears, such as passive landing leg using honey-comb-core, are not sophisticated enough to land safely and precisely on rough terrain. Therefore, the authors propose to introduce active landing leg using variable damper in order to make secure and precise landing on any rough terrain on planetary body. In this paper, numerical simulation of the touchdown is performed by using 2DOF lander model with and without active control and lunar soil mechanics. From the result, we present the effect of surface parameter for the landing, evaluate the active landing leg and summarize the possibility of secure and precise landing with active landing leg.","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: AA0064734055","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":"東京大学"},{"subitem_text_value":"宇宙航空研究開発機構"},{"subitem_text_value":"宇宙航空研究開発機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"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":"田口, 勝也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"橋本, 樹明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大槻, 真嗣"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Taguchi, Katsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, Tatsuaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Otsuki, Masatsugu","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":"Touchdown Dynamics Analysis and Possibility of Secure and Precise Landing with Active Controlled Landing Gear","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Touchdown Dynamics Analysis and Possibility of Secure and Precise Landing with Active Controlled Landing Gear","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":"7360","relation_version_is_last":true,"title":["Touchdown Dynamics Analysis and Possibility of Secure and Precise Landing with Active Controlled Landing Gear"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:40:43.573295+00:00"}
