Recently fiber reinforced plastic (FRP) laminates came to be widely used as the primary structures of airplanes, which can control the mechanical properties and the eigen-frequencies by the laminate stacking sequence, ply orientation, and so on. Moreover, if curved paths of the fibers can be allowed, the structure can be designed more lightly and accordingly the airplane can show higher performances. To this end a tailored fiber placement (TFP) method using an embroidery machine was suggested. In this paper, feasibility of the TFP with the embroidery machine was examined for the eigen-frequency control of a cantilever rectangular laminate plate as a preliminary study of applications of the TFP method to the flutter problems. First, the method to estimate material constants of a TFP layer and substrate layers was proposed according to the classical laminate theory. Then, using the obtained material constants an optimal fiber bundle path was calculated for the cantilever rectangular laminate plate with a size of 150mm×100mm×2mm so that the frequency margin between the fundamental torsional and bending modes was maximized keeping the fundamental frequency of the bending mode more than 80 Hz. Experimental verification was also performed. The prediction agreed well with the experiment, differing by approximately 10% due to the manufacturing error and the assumptions. Next to design further light structures a method that the stiffening fiber bundles were locally placed was proposed. The optimization result of the local TFP showed it had a comparable performance yet less than a half of weight of the reinforcing fiber bundles compared to the global TFP. These results indicate feasibility of application of the TFP to the aeroelastic problems.","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: AA1630046011","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-16-008E","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(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"},{"subitem_text_value":"名古屋大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Nagoya University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"池田, 忠繁"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岡, 功介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"西田, 竜也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ikeda, Tadashige","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oka, Kosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishida, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"AA1630046011.pdf","filesize":[{"value":"911.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630046011.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3404/files/AA1630046011.pdf"},"version_id":"0a8a0c3b-8abd-4ffc-8780-e2682f21381a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"eigen-frequency","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"CFRP","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tailored fiber placement","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"embroidery","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flutter","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Eigen-frequency control design of cfrp structures using an embroidery machine","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Eigen-frequency control design of cfrp structures using an embroidery machine","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["824","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-27"},"publish_date":"2017-04-27","publish_status":"0","recid":"3404","relation_version_is_last":true,"title":["Eigen-frequency control design of cfrp structures using an embroidery machine"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:03:20.929186+00:00"}
