Elements of absorber are modeled by 3D finite element, which having complex density and complex volume elasticity. By expanding the solution of complex eigenvalue problem with small parameter, equations of motion are derived using first order of asymptotic components. From the equations, contribution of damping elements on modal damping is derived in consideration of multiple modes. The sound absorber is arranged in muffler according to this contribution. It proposed a positioning method of sound absorbers within the limits of design feasible region and it applied to the expansion type muffler and availability of this method is verified.","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/110007119852/","subitem_relation_type_select":"URI"}}]},"item_6_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"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_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12120184","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":"津川, 純一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岡部, 雅哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"榎本, 秀喜"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒沢, 良夫"}],"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":"E_yamaguchi_2008-604.pdf","filesize":[{"value":"726.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"E_yamaguchi_2008-604.pdf","url":"https://gunma-u.repo.nii.ac.jp/record/2988/files/E_yamaguchi_2008-604.pdf"},"version_id":"e160de68-708f-454e-95d6-c1c47350ef49"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Damping","subitem_subject_scheme":"Other"},{"subitem_subject":"Finite Element Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Computer aided Engineering","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":"604 固有ベクトルと減衰寄与率を用いたマフラーのFEM音響解析と吸音性能向上","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"604 固有ベクトルと減衰寄与率を用いたマフラーのFEM音響解析と吸音性能向上"},{"subitem_title":"604 FEA of acoustic properties for a muffler using eigenvectors and damping contribution to improve sound absorption","subitem_title_language":"en"}]},"item_type_id":"6","owner":"2","path":["576"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-06-25"},"publish_date":"2010-06-25","publish_status":"0","recid":"2988","relation_version_is_last":true,"title":["604 固有ベクトルと減衰寄与率を用いたマフラーのFEM音響解析と吸音性能向上"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-19T13:15:15.305893+00:00"}
