There is the case that the damage occurs by the coupled vibration. The response magnification is obtained from the modal natural frequency and the modal damping ratio of the coupled system in the seismic design. Therefore, the modal natural frequency and the modal damping ratio of the coupled system are required. The natural frequency and the damping ratio of the support and the structure are abtained during the initial design process or by a shaking test. However, the modal natural frequency and the modal damping ratio of the coupled system are not easily obtained. The modal natural frequency of the coupled system can be calculated from theoretical equation, but the modal damping ratio cannot be easily calculated. In the present study, an equation to calculate the modal damping ratio of the coupled system with classic damping is presented. In addition, a simple equation to calculate the modal damping ratio with a non-classic damping system is proposed. This equation is evaluated theoretically. The proposed equation is useful for obtaining the modal damping ratio without performing eigenvalue analysis or a shaking test.","subitem_description_type":"Abstract"}]},"item_119_description_21":{"attribute_name":"注記","attribute_value_mlt":[{"subitem_description":"rights: 社団法人日本機械学会\nrights: 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\nrelation: IsVersionOf:http://ci.nii.ac.jp/naid/110007008094/","subitem_description_type":"Other"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"社団法人日本機械学会"}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875024","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[出版社版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"WATANABE, Tetsuya"},{"subitem_text_value":"TOMODA, Akinori"},{"subitem_text_value":"TANAKA, Kihachiro"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1003349"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科人間支援・生産科学部門"},{"subitem_text_value":"埼玉大学大学院理工学研究科"},{"subitem_text_value":"埼玉大学大学院理工学研究科人間支援・生産科学部門"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Division of Mechanical Engineering and Science, Saitama University"},{"subitem_text_value":"Division of Mechanical Engineering and Science, Saitama University"},{"subitem_text_value":"Division of Mechanical Engineering and Science, Saitama University"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2008-1"}]},"item_119_version_type_28":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡邉, 鉄也"},{"creatorName":"ワタナベ, テツヤ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"鞆田, 顕章"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田中, 基八郎"},{"creatorName":"タナカ, キハチロウ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1003349.pdf","filesize":[{"value":"574.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1003349.pdf","url":"https://sucra.repo.nii.ac.jp/record/13764/files/A1003349.pdf"},"version_id":"db491fa0-ffab-46d2-a047-4c34b8e1d46e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Structure","subitem_subject_scheme":"Other"},{"subitem_subject":"Support","subitem_subject_scheme":"Other"},{"subitem_subject":"Coupled System","subitem_subject_scheme":"Other"},{"subitem_subject":"Estimation of Dynamic Parameters","subitem_subject_scheme":"Other"},{"subitem_subject":"Seismic 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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"2つの1自由度系減衰比を用いた連成系減衰比の簡易推定(機械力学,計測,自動制御)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"2つの1自由度系減衰比を用いた連成系減衰比の簡易推定(機械力学,計測,自動制御)"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-02-24"},"publish_date":"2010-02-24","publish_status":"0","recid":"13764","relation_version_is_last":true,"title":["2つの1自由度系減衰比を用いた連成系減衰比の簡易推定(機械力学,計測,自動制御)"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:24:25.040786+00:00"}
