The observed characteristics of the flight are : 1) The flight speed is rather low. lt ranges from 0.4m/s to 0.9m/s in our experiments. 2) The inclinations of the stroke planes are small. It is 10～15 deg for the forewing and 0～30 deg for the hindwing. 3) The flapping amplitude of the wing is almost twice as large as that of a dragonfly for the fore and hindwing respectively. 4) The phase difference between fore and hind pairs of wings is about -100 deg. lt is 60～90 deg in the flight of a dragonfly. We use the Fourier analysis to make clear the beating mechanism of wings ; the flapping motion can be expressed by the first harmonic of a Fourier expansion series, while the higher harmonics were needed to simulate the feathering motion of the wing.","subitem_description_type":"Other"}]},"item_2_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"7","subitem_description_type":"Other"}]},"item_2_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00001511998","subitem_description_type":"Other"}]},"item_2_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_2_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00159741","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_19":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03876055","subitem_source_identifier_type":"ISSN"}]},"item_2_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京工芸大学工学部画像工学科"}]},"item_2_title_3":{"attribute_name":"論文名よみ","attribute_value_mlt":[{"subitem_title":"イトトンボ ノ ヒコウ カイセキ"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 真知子"},{"creatorName":"サトウ, マチコ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"574","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SATO, Machiko","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"575","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-04-21"}],"displaytype":"detail","filename":"KJ00001511998.pdf","filesize":[{"value":"596.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00001511998.pdf","url":"https://kougei.repo.nii.ac.jp/record/223/files/KJ00001511998.pdf"},"version_id":"3b833e73-c898-4119-8eed-9f93f15564e1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"イトトンボの飛行解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イトトンボの飛行解析"},{"subitem_title":"An Analysis of Damselfly Flight","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["49"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-21"},"publish_date":"2017-04-21","publish_status":"0","recid":"223","relation_version_is_last":true,"title":["イトトンボの飛行解析"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T14:22:32.135055+00:00"}
