The revision of the trailing edge mentioned above by grinding could almost arrest the singing. However there are many cases where recent propeller singing cannot be extinguished by the usual measure. In this study, the characeristics of recent singing and its preventive measures are considered using FFT analysis of noise occured in some large ships. In consequence, we developed a new anti-singing design which leads to good results on some applied ships.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学工学部研究報告 Vol.28(50) p.15-19, 1998","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"108346","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kawazoe, Tsuyoshi"}]},{"nameIdentifiers":[{"nameIdentifier":"108347","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakashima, Touru"}]},{"nameIdentifiers":[{"nameIdentifier":"108348","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nishikido, Shingo"}]},{"nameIdentifiers":[{"nameIdentifier":"108349","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Leong, Lee Kim"}]}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178418","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02860902","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"P00015-P00019"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"川添, 強"}],"nameIdentifiers":[{"nameIdentifier":"108339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中島, 徹"}],"nameIdentifiers":[{"nameIdentifier":"108340","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"錦戸, 慎吾"}],"nameIdentifiers":[{"nameIdentifier":"108341","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Leong, Lee Kim"}],"nameIdentifiers":[{"nameIdentifier":"108342","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":"2020-12-24"}],"displaytype":"detail","filename":"KJ00000136368.pdf","filesize":[{"value":"337.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00000136368.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/25582/files/KJ00000136368.pdf"},"version_id":"4eda41b2-bf63-416c-b7af-a819983cf873"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Marine Propeller","subitem_subject_scheme":"Other"},{"subitem_subject":"Singing","subitem_subject_scheme":"Other"},{"subitem_subject":"Karman Vortex","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural Frequency","subitem_subject_scheme":"Other"},{"subitem_subject":"Blade design","subitem_subject_scheme":"Other"}]},"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":"最近のプロペラ鳴音の特徴とその防止法の研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"最近のプロペラ鳴音の特徴とその防止法の研究"}]},"item_type_id":"3","owner":"2","path":["1922"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-01-26"},"publish_date":"2007-01-26","publish_status":"0","recid":"25582","relation_version_is_last":true,"title":["最近のプロペラ鳴音の特徴とその防止法の研究"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-15T23:30:03.020363+00:00"}
