Here, it is beneficial for heavy locomotives to employ forced steering trucks to reduce the lateral force between the wheel and rail during curve negotiation. This paper deals with numerical analysis about curving behaivor and running stability of the forced steering three-axle trucks. In the analysis, wheel lateral forces and the critical speed for stable running are examined parametrically varying leverage ratio and stiffness in the steering link, wheel tread conicity and wheelset supporting stiffness. In addition, the possibility for improving the critical speed is investigated. The results show that the proper value for the leverage ratio changes with curve radius, and that higher leverage ratio can make the running stability worse under large steering link stiffness. It is also shown that the proper tuning of the wheelset supporting stiffness increases the critical speed keeping the lower lateral force brought by the forced steering mechanism.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"45677","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tanifuji, Katsuya"}]},{"nameIdentifiers":[{"nameIdentifier":"45678","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Takefumi"}]},{"nameIdentifiers":[{"nameIdentifier":"45679","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saima, Toru"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本機械学会"}]},"item_5_relation_31":{"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/110002383513","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本機械学会 / 本文データは学会の許諾に基づくCiNiiからの複製である"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_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_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875024","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"谷藤, 克也"}],"nameIdentifiers":[{"nameIdentifier":"45674","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 剛史"}],"nameIdentifiers":[{"nameIdentifier":"45675","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"斎間, 亨"}],"nameIdentifiers":[{"nameIdentifier":"45676","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":"2019-07-30"}],"displaytype":"detail","filename":"9_0128.pdf","filesize":[{"value":"658.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"9_0128.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3834/files/9_0128.pdf"},"version_id":"dc783adc-3b60-4639-b270-4b1ef8d9099f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Railway","subitem_subject_scheme":"Other"},{"subitem_subject":"Stability","subitem_subject_scheme":"Other"},{"subitem_subject":"Critical Speed","subitem_subject_scheme":"Other"},{"subitem_subject":"Numerical Simulation","subitem_subject_scheme":"Other"},{"subitem_subject":"Eigenvalue Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Curve Negotiation","subitem_subject_scheme":"Other"},{"subitem_subject":"Wheel","subitem_subject_scheme":"Other"},{"subitem_subject":"Rail Lateral Force","subitem_subject_scheme":"Other"},{"subitem_subject":"Forced Steering","subitem_subject_scheme":"Other"},{"subitem_subject":"Locomotive","subitem_subject_scheme":"Other"},{"subitem_subject":"Three-Axle Truck","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":"強制操舵方式による機関車用三軸台車の曲線通過","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"強制操舵方式による機関車用三軸台車の曲線通過"},{"subitem_title":"強制操舵方式による機関車用三軸台車の曲線通過","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","425"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-04-08"},"publish_date":"2008-04-08","publish_status":"0","recid":"3834","relation_version_is_last":true,"title":["強制操舵方式による機関車用三軸台車の曲線通過"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:52.116915+00:00"}
