It is necessary for such a rotating shaft to pass resonance points under the rated speed with a small deflection safely at the start or end of its operation. In this paper, nonstationary vibration characteristics of a rotating shaft with nonlinear spring characteristics are investigated concerning the following critical speeds: a major critical speed, the critical speeds of subharmonic oscillations of orders 1/2 and 1/3, and a critical speed of a summed-and-differential harmonic oscillation. The rotating speed is changed with a constant acceleration. Especially, the influences of the angular acceleration λ, the initial angular positionΨ[0] of a rotor unbalance, the initial rotating speedω[s] and the initial disturbance on the maximum amplitude are investigated.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memsenu.44.1.1", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "School of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0919-0805", "subitem_source_identifier_type": "PISSN"}]}, "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": "Ishida, Yukio", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101864", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ikeda, Takashi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101865", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Yamamoto, Toshio", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101866", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Murakami, Shin", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "101867", "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": "2020-10-23"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "44-1-01.pdf", "filesize": [{"value": "5.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 5500000.0, "url": {"label": "44-1-01.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/30674/files/44-1-01.pdf"}, "version_id": "b7ece29c-f21d-48fc-9620-4028dabeff62"}]}, "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Nonstationary vibrations of a rotating shaft with nonlinear spring characteristics during acceleration through critical speeds", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Nonstationary vibrations of a rotating shaft with nonlinear spring characteristics during acceleration through critical speeds", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2541"], "permalink_uri": "https://doi.org/10.18999/memsenu.44.1.1", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-10-23"}, "publish_date": "2020-10-23", "publish_status": "0", "recid": "30674", "relation": {}, "relation_version_is_last": true, "title": ["Nonstationary vibrations of a rotating shaft with nonlinear spring characteristics during acceleration through critical speeds"], "weko_shared_id": -1}
