The simulated results on the dynamic response are discussed in terms of railpad force, sleeper-ballast interaction force, sleeper acceleration and ballast acceleration. The ballast and substrate are modeled as 2D elastodynamic bodies. The accuracy of the vibration model is investigated based on the comparison with in-situ measurements. In the railpad force and the sleeper-ballast interaction force, the impact responses are accurately simulated; the post-impact responses obtained by the present model have the differences in terms of period and amplitude in contrast to the measurements. The sleeper acceleration has the different peaks in the spectral space between the numerical results and the measurements; the intensity of the response shows good agreement in the frequency range under 200Hz. The ballast layer is an assemblage of crushed hard stone, of which the particle action influences to the macroscopic dynamic response of the ballast layer. Therefore, though the present model can evaluate the maximal acceleration level, it may simulate the spectrum distribution sufficiently.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39286","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Koro, Kazuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"39287","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Abe, Kazuhisa"}]},{"nameIdentifiers":[{"nameIdentifier":"39288","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ishida, Makoto"}]},{"nameIdentifiers":[{"nameIdentifier":"39289","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Suzuki, Takahiro"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会"}]},"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":"AA11311063","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13459139","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"紅露, 一寛"}],"nameIdentifiers":[{"nameIdentifier":"39282","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"阿部, 和久"}],"nameIdentifiers":[{"nameIdentifier":"39283","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"石田, 誠"}],"nameIdentifiers":[{"nameIdentifier":"39284","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"鈴木, 貴洋"}],"nameIdentifiers":[{"nameIdentifier":"39285","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":"jsceam2005.pdf","filesize":[{"value":"874.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"jsceam2005.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2824/files/jsceam2005.pdf"},"version_id":"55c097d3-6250-40eb-abd0-fbc9acd90709"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"rail joint","subitem_subject_scheme":"Other"},{"subitem_subject":"track-substrate dynamic interaction","subitem_subject_scheme":"Other"},{"subitem_subject":"modelling of track","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":"レール継目部列車走行試験の有限要素シミュレーションとその再現性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"レール継目部列車走行試験の有限要素シミュレーションとその再現性"},{"subitem_title":"レール継目部列車走行試験の有限要素シミュレーションとその再現性","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","470"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-06-21"},"publish_date":"2007-06-21","publish_status":"0","recid":"2824","relation_version_is_last":true,"title":["レール継目部列車走行試験の有限要素シミュレーションとその再現性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:02.996714+00:00"}
