However, in a practical view point, these diagnosis systems have the following defects: (1)The probability that a resonance due to a crack occurs in the rated speed range is small. (2)It is very dangerous to observe vibration characteristics in resonance ranges spending long time. In this paper, we propose a new method utilizing the changes of vibration phenomena due to a crack in a nonstationary oscillation during start up of a rotating machinery. The advantage of this method is that we can check the signals denoting the occurrence of a crack in a wide speed range by a single sweep and also can avoid the operation in dangerous resonance ranges. Moreover, the validity of the proposed method is shown through numerical simulations and experiments.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/9039"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"}]},"item_10_relation_43":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110004659156/","subitem_relation_type_select":"URI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会","subitem_rights_language":"ja"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである。","subitem_rights_language":"ja"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5024","subitem_source_identifier_type":"PISSN"}]},"item_10_text_14":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_text_value":"application/pdf"}]},"item_1615787544753":{"attribute_name":"出版タイプ","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":"石田, 幸男","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20418","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ISHIDA, Yukio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20419","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"劉, 軍","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20420","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"LIU, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20421","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井上, 剛志","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20422","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"INOUE, Tsuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20423","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"近藤, 英男","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20424","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KONDO, Hideo","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20425","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":"2018-02-19"}],"displaytype":"detail","filename":"JsMecEngC_72-714-316.pdf","filesize":[{"value":"747.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JsMecEngC_72-714-316.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/7359/files/JsMecEngC_72-714-316.pdf"},"version_id":"2d359efc-49da-4d29-b4dd-acfd6535f9b1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Vibration of Rotating Body","subitem_subject_scheme":"Other"},{"subitem_subject":"Nonstationary Vibration","subitem_subject_scheme":"Other"},{"subitem_subject":"Diagnosis","subitem_subject_scheme":"Other"},{"subitem_subject":"Creaked Rotor","subitem_subject_scheme":"Other"},{"subitem_subject":"Unbalance","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"非定常振動によるロータのクラックの検出 (不つりあいの方向による非定常振動の最大振幅の変化)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"非定常振動によるロータのクラックの検出 (不つりあいの方向による非定常振動の最大振幅の変化)","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-27"},"publish_date":"2007-11-27","publish_status":"0","recid":"7359","relation_version_is_last":true,"title":["非定常振動によるロータのクラックの検出 (不つりあいの方向による非定常振動の最大振幅の変化)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:53.082124+00:00"}
