When both ends of the rotor are supported by self-aligning double-row ball bearings, this geometric nonlinearity appears due to the stiffening effort in elongation of the shaft if the movements of the bearings in the longitudinal direction are restricted. The nonlinearity is symmetric when the rotor is supported vertically, and is asymmetric when it is supported horizontally. Because the rotor is slender, the natural frequency of a forward whirling mode p_fn and that of a backward whirling mode p_bn have the relation of internal resonance p_fn:p_bn=1:(-1). Due to the influences of the internal resonance, the complicated resonance phenomena such as Hopf bifurcation, an almost periodic motion, the appearance new branches and the disappearance of unstable region, occur. These phenomena were clarified theoretically and experimentally. The influences of the nonlinearity, the unbalance, the damping, and a lateral force on the vibration characteristics are also examined.","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/2237/9051"}]},"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/110004865194/","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":"長坂, 今夫","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20468","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"NAGASAKA, Imao","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20469","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石田, 幸男","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20470","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ISHIDA, Yukio","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20471","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"劉, 軍","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20472","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"LIU, Jun","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"服部, 卓也","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"20474","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HATTORI, Takuya","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"20475","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_67-664-3688.pdf","filesize":[{"value":"913.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JsMecEngC_67-664-3688.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/7371/files/JsMecEngC_67-664-3688.pdf"},"version_id":"9328cd00-d7f3-4d4f-86fd-42dd99568a70"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Nonlinear Vibration","subitem_subject_scheme":"Other"},{"subitem_subject":"Continuous Asymmetrical Rotor","subitem_subject_scheme":"Other"},{"subitem_subject":"Gravity","subitem_subject_scheme":"Other"},{"subitem_subject":"Internal Resonance","subitem_subject_scheme":"Other"},{"subitem_subject":"Bifurcation","subitem_subject_scheme":"Other"},{"subitem_subject":"Almost Periodic Motion","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":"幾何学的非線形ばね特性をもつ連続偏平軸の強制振動 (主危険速度と二次的危険速度付近)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"幾何学的非線形ばね特性をもつ連続偏平軸の強制振動 (主危険速度と二次的危険速度付近)","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-11-29"},"publish_date":"2007-11-29","publish_status":"0","recid":"7371","relation_version_is_last":true,"title":["幾何学的非線形ばね特性をもつ連続偏平軸の強制振動 (主危険速度と二次的危険速度付近)"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T03:52:30.207625+00:00"}
