In this analysis, the sound absorbers can have arbitrary shapes and can be located anywhere in the fields. The fields involve gas and sound absorbers which are modeled using Finite Element Method. A new three-dimensional element are developed for the absorbers. This element has two damping parameters which are complex density and complex volume elasticity. The elements are constructed, and then the corresponding simultaneously coupled equations are solved to obtain the frequency response. Further, a new expression is also derived to get distribution of contribution to modal damping for each element. These approachs are applied to three-dimensional rooms where the absorbers exist in different positions. The results are compared with the experiments carried out by Utsuno and are discussed.","subitem_description_type":"Abstract"}]},"item_6_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_6_relation_43":{"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/110002378303/","subitem_relation_type_select":"URI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会"},{"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"}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5024","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00187463","subitem_source_identifier_type":"NCID"}]},"item_6_version_type_15":{"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":"山口, 誉夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒沢, 良夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松村, 修二"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-25"}],"displaytype":"detail","filename":"C68_1.pdf","filesize":[{"value":"572.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"C68_1.pdf","url":"https://gunma-u.repo.nii.ac.jp/record/3448/files/C68_1.pdf"},"version_id":"646079a7-56ce-47f0-8260-bfa434056855"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Damping","subitem_subject_scheme":"Other"},{"subitem_subject":"Damping Material","subitem_subject_scheme":"Other"},{"subitem_subject":"Automobile","subitem_subject_scheme":"Other"},{"subitem_subject":"Noise","subitem_subject_scheme":"Other"},{"subitem_subject":"Computer Aided Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Sound Absorbing Material","subitem_subject_scheme":"Other"},{"subitem_subject":"Modal Strain and Kinetic Energy Method","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":"閉空間領域内に吸音体を有する三次元音場の減衰特性の有限要素解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"閉空間領域内に吸音体を有する三次元音場の減衰特性の有限要素解析"},{"subitem_title":"Damping Analysis of 3D Acoustic Fields Involving Sound Absorbing Materials Using FEM","subitem_title_language":"en"}]},"item_type_id":"6","owner":"2","path":["576"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-02-06"},"publish_date":"2008-02-06","publish_status":"0","recid":"3448","relation_version_is_last":true,"title":["閉空間領域内に吸音体を有する三次元音場の減衰特性の有限要素解析"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-19T13:01:01.118296+00:00"}
