An acoustics field in inner or exterior problems of harmonic vibration is governed by the Helmholtz equation. It can be solved by a boundary condition and an initial condition being given. Unknown values of acoustic pressure on the boundary are analyzed by the boundary element method using boundary conditions. After this procedure, the values of acoustic pressure at the inside point can be calculated from those of the boundary. This procedure allowed substantial saving of memory. Analysis with a personal computer became possible. According to these results, it was shown that the calculations can be carried out sufficiently with a small computer in spite of the small memory capacity. Small computers, which are very popular, will become an effective tool in numerical simulation with boundary element method.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0004168028","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-19","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京理科大学 理学部　物理学科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Science University of Tokyo Department of Physics, Faculty of Science"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柳沢, 三憲"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagizawa, Mitsunori","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-10"}],"displaytype":"detail","filename":"nalsp0019028.pdf","filesize":[{"value":"269.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nalsp0019028.pdf","url":"https://jaxa.repo.nii.ac.jp/record/37714/files/nalsp0019028.pdf"},"version_id":"38c884d5-a78c-462c-b82d-a06cfc6940bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"音場解析","subitem_subject_scheme":"Other"},{"subitem_subject":"音響解析","subitem_subject_scheme":"Other"},{"subitem_subject":"騒音解析","subitem_subject_scheme":"Other"},{"subitem_subject":"音響放射","subitem_subject_scheme":"Other"},{"subitem_subject":"音響振動","subitem_subject_scheme":"Other"},{"subitem_subject":"音響インピーダンス","subitem_subject_scheme":"Other"},{"subitem_subject":"ヘルムホルツ方程式","subitem_subject_scheme":"Other"},{"subitem_subject":"解法","subitem_subject_scheme":"Other"},{"subitem_subject":"BEM","subitem_subject_scheme":"Other"},{"subitem_subject":"境界要素法","subitem_subject_scheme":"Other"},{"subitem_subject":"共鳴箱","subitem_subject_scheme":"Other"},{"subitem_subject":"騒音抑制","subitem_subject_scheme":"Other"},{"subitem_subject":"騒音軽減","subitem_subject_scheme":"Other"},{"subitem_subject":"sound field analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic field analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"noise analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic radiation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic vibration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic impedance","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Helmholz equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solution method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"BEM","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"boundary element method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"resonance chamber","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"noise suppression","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"境界要素法による3次元音響解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"境界要素法による3次元音響解析"}]},"item_type_id":"5","owner":"1","path":["1891","1915"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"37714","relation_version_is_last":true,"title":["境界要素法による3次元音響解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:14:16.827085+00:00"}
