Previously several methods were proposed to reduce the stress concentration through improving bolts and nuts profile. Among those methods, tapering threads have been widely used in mechanical structures. Those types of threads are called CD bolts, which were proposed by Nishida as an effective method for stress reduction. Several experimental studies indicated that CD bolts have higher fatigue strength although little FEM analyses is available. In this study, therefore, the bolted joint with tapered threads is analyzed with the finite element method, and stress reduction effect of CD bolts is discussed with varying geometrical conditions. The reduction of the stress concentration is realized by tapering bolt thread. Then, it is found that the stress reduction is notable when the height of bolt threads is reduced significantly near the bolt heat and the nut is closer to the bolt head. According to those results, optimum conditions for stress reduction are discussed. Then, it is shown that the maximum stress can be decreased by 20% compared with the cases of standard bolts and nuts.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/10_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版社","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1299/kikaia.74.1305","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"著作権関連情報","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_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018742X","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1884-8338","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"0387-5008","subitem_source_identifier_type":"PISSN"}]},"item_21_text_63":{"attribute_name":"連携ID","attribute_value_mlt":[{"subitem_text_value":"2429"}]},"item_21_text_64":{"attribute_name":"業績ID","attribute_value_mlt":[{"subitem_text_value":"A36B6004DC5CBF77492576AA0082E098"}]},"item_21_version_type_58":{"attribute_name":"出版タイプ","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":"久原, 昌浩","creatorNameLang":"ja"},{"creatorName":"Kuhara, Masahiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"肖, 陽","creatorNameLang":"ja"},{"creatorName":"Xiao, Yang","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNames":[{}]}],"creatorNames":[{"creatorName":"Noda, Nao-Aki","creatorNameLang":"en"},{"creatorName":"野田, 尚昭","creatorNameLang":"ja"},{"creatorName":"ノダ, ナオアキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2010-07-12"}],"displaytype":"detail","filename":"110006975976.pdf","filesize":[{"value":"891.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110006975976.pdf","url":"https://kyutech.repo.nii.ac.jp/record/3550/files/110006975976.pdf"},"version_id":"4296c637-f427-4441-9348-e91bdd820fb1"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Finite Element Method","subitem_subject_scheme":"Other"},{"subitem_subject":"Stress Concentration","subitem_subject_scheme":"Other"},{"subitem_subject":"Machine Element","subitem_subject_scheme":"Other"},{"subitem_subject":"Fixing Element","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":"ねじ山高さの漸減により応力集中を緩和させる条件","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ねじ山高さの漸減により応力集中を緩和させる条件","subitem_title_language":"ja"},{"subitem_title":"The Reduction of Stress Concentration by Tapering Threads","subitem_title_language":"en"}]},"item_type_id":"21","owner":"14","path":["24"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-07-12"},"publish_date":"2010-07-12","publish_status":"0","recid":"3550","relation_version_is_last":true,"title":["ねじ山高さの漸減により応力集中を緩和させる条件"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-12-01T07:45:06.771150+00:00"}
