When the excitation frequency is constant, it is well known that an undamped dynamic vibration absorber is very effective to attenuate the vibration amplitude of the primary system. However, when the excitation frequency fluctuates in small range, such an undamped absorber does not always suppress the vibration amplitude. In this paper, we find out that upper limit of the vibration amplitude of the primary system can be estimated easily by using the imaginary part of the dynamic stiffness of the absorber. We derive very simple equations which give the optimum natural frequency and damping ratio of the absorber for given excitation frequency range. Calculation results of the frequency response for some examples designed by the proposed method are demonstrated and they show the usefulness of the proposed method.", "subitem_description_type": "Abstract"}]}, "item_2_publisher_35": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "item_2_relation_46": {"attribute_name": "異版である", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://ci.nii.ac.jp/naid/110006535078/", "subitem_relation_type_select": "URI"}}]}, "item_2_rights_14": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "社団法人日本機械学会。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。"}]}, "item_2_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00187463", "subitem_source_identifier_type": "NCID"}]}, "item_2_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0387-5024", "subitem_source_identifier_type": "ISSN"}]}, "item_2_version_type_18": {"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": "井上, 喜雄"}], "nameIdentifiers": [{"nameIdentifier": "205", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "芝田, 京子"}], "nameIdentifiers": [{"nameIdentifier": "206", "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": "2019-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "nkr_73_736_3143.pdf", "filesize": [{"value": "673.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 673600.0, "url": {"label": "nkr_73_736_3143.pdf", "url": "https://kutarr.kochi-tech.ac.jp/record/56/files/nkr_73_736_3143.pdf"}, "version_id": "2a7ed88c-928a-462e-9e67-e56228bd6f4e"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Dynamic Absorber", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Damping", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Forced Vibration", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Optimal Design", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Dynamic Stiffness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Robust 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": "加振周波数の変動範囲を考慮した動吸振器の設計法", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "加振周波数の変動範囲を考慮した動吸振器の設計法"}]}, "item_type_id": "2", "owner": "2", "path": ["5"], "permalink_uri": "http://hdl.handle.net/10173/521", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-08-27"}, "publish_date": "2010-08-27", "publish_status": "0", "recid": "56", "relation": {}, "relation_version_is_last": true, "title": ["加振周波数の変動範囲を考慮した動吸振器の設計法"], "weko_shared_id": -1}
