Especially, the self-excited vibration to be called as oil whirl generated in sliding bearing is studied in the current paper. Four methods like trajectory analysis, frequency response function analysis, particle numbers of wear debris and SOAP-T based on lubricant analysis are analyzed to clarify the vibration characteristics of oil whirl. The oil whirl in a sliding bearing is a characteristic self-oscillation, which occurs at a rotation speed less than the twice of the critical speed of the experimental system. In addition, when oil whirl is generated in a sliding bearing, the frequen y response in all\ndomains of frequency is suddenly become larger compared to that in the case of normal conditions. It seems that simultaneous development of oil whirl generates the large damage to the rotary machinery system. Furthermore,the amount of whirling to the shaft generated by the oil whirl are identified large in the horizontal, vertical and axial directions of sliding bearing. Particularly, the amount of whirling in the horizontal direction is identified larger, because, there is no suppression as gravity and structural barrier in this direction like that in the vertical and in the axial directions.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57348/0002010411","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan Fisheries Research and Education Agency","subitem_publisher_language":"en"},{"subitem_publisher":"水産研究・教育機構","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"fish-u_k_71-3_1","subitem_relation_type_select":"Local"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00124678","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0370-9361","subitem_source_identifier_type":"PISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"太田, 博光","creatorNameLang":"ja"}],"familyNames":[{"familyName":"太田","familyNameLang":"ja"}],"givenNames":[{"givenName":"博光","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"清水, 慧","creatorNameLang":"ja"}],"familyNames":[{"familyName":"清水","familyNameLang":"ja"}],"givenNames":[{"givenName":"慧","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"福井 良輔","creatorNameLang":"ja"}],"familyNames":[{"familyName":"福井","familyNameLang":"ja"}],"givenNames":[{"givenName":"良輔","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"長橋, 尚也","creatorNameLang":"ja"}],"familyNames":[{"familyName":"長橋","familyNameLang":"ja"}],"givenNames":[{"givenName":"尚也","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"山田 雄太","creatorNameLang":"ja"}],"familyNames":[{"familyName":"山田","familyNameLang":"ja"}],"givenNames":[{"givenName":"雄太","givenNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"fish-u_k_71-3_1.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://fra.repo.nii.ac.jp/record/2010411/files/fish-u_k_71-3_1.pdf"},"version_id":"d3c1b267-e192-4496-a0a1-77b7e364e04e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Self-Excited Vibration; Oil Whirl, sliding bearing; frequency response; lubricant analysis; SOAP-T.","subitem_subject_language":"en","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":"自励振動オイルホワールの周波数応答と潤滑油解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"自励振動オイルホワールの周波数応答と潤滑油解析","subitem_title_language":"ja"},{"subitem_title":"Frequency respose and lubricant analysis of oil whirl in kind of self excited vibration generated in sliding bearings","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["15","26"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-07-25"},"publish_date":"2024-07-25","publish_status":"0","recid":"2010411","relation_version_is_last":true,"title":["自励振動オイルホワールの周波数応答と潤滑油解析"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-08-22T07:13:18.525193+00:00"}
