To this end, the stationary harmonic loading problem and the interaction between a moving wheel and a track are analyzed. As the sleeper arrangements, three cases of the regular spacing, stochastic distribution obtained by in-situ measurements and an optimal distribution are considered. Through these numerical experiments, the vibration and noise reductions by the introduction of the irregularity into the sleeper spacing are evaluated based on resonance modes at frequencies lower than lOOOHz.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"41643","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Kazuhisa"}]},{"nameIdentifiers":[{"nameIdentifier":"41644","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koro, Kazuhiro"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright(C)2014 公益社団法人土木学会"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sodbilig, Batjargal"}],"nameIdentifiers":[{"nameIdentifier":"41640","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"阿部, 和久"}],"nameIdentifiers":[{"nameIdentifier":"41641","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"紅露, 一寛"}],"nameIdentifiers":[{"nameIdentifier":"41642","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":"18_23-30.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"18_23-30.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/3244/files/18_23-30.pdf"},"version_id":"ab0e58c1-b82f-4c5b-ab7b-125f9ceb6694"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sleeper spacing","subitem_subject_scheme":"Other"},{"subitem_subject":"wheel/track interaction","subitem_subject_scheme":"Other"},{"subitem_subject":"vibration reduction","subitem_subject_scheme":"Other"},{"subitem_subject":"noise reduction","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":"まくらぎ配置がレールの振動・騒音特性に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"まくらぎ配置がレールの振動・騒音特性に及ぼす影響"},{"subitem_title":"まくらぎ配置がレールの振動・騒音特性に及ぼす影響","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-12-17"},"publish_date":"2014-12-17","publish_status":"0","recid":"3244","relation_version_is_last":true,"title":["まくらぎ配置がレールの振動・騒音特性に及ぼす影響"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:24.725208+00:00"}
