Also, track dynamic behaviors such as dynamic wheel loads, rail seat forces, rail and sleeper displacements excited by vehicles running at a rail joint at the speed up to 70km/h were measured. On the other hand, the authors established a track dynamic model considering the excitation caused by wheels transferring at the discontinuity of fish plate rail joints. Then the measured and analytical results were compared and a good agreement was obtained. Finally the influence of rail surface irregularity, longitudinal profile of dip joint and the gap of fish plate joint on dynamic wheel loads was studied.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "41683", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Takahiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "41684", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishida, Makoto"}]}, {"nameIdentifiers": [{"nameIdentifier": "41685", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Abe, Kazuhisa"}]}, {"nameIdentifiers": [{"nameIdentifier": "41686", "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": "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_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "13476092", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "鈴木, 貴洋"}], "nameIdentifiers": [{"nameIdentifier": "41679", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "石田, 誠"}], "nameIdentifiers": [{"nameIdentifier": "41680", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "阿部, 和久"}], "nameIdentifiers": [{"nameIdentifier": "41681", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "紅露, 一寛"}], "nameIdentifiers": [{"nameIdentifier": "41682", "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", "download_preview_message": "", "file_order": 0, "filename": "8_35-40.pdf", "filesize": [{"value": "718.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 718500.0, "url": {"label": "8_35-40.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3251/files/8_35-40.pdf"}, "version_id": "6a8c0c68-6201-483a-98e0-52821d97783f"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "rail dip joint", "subitem_subject_scheme": "Other"}, {"subitem_subject": "track site measurements", "subitem_subject_scheme": "Other"}, {"subitem_subject": "vehicle/track interaction", "subitem_subject_scheme": "Other"}, {"subitem_subject": "wheel load variation", "subitem_subject_scheme": "Other"}, {"subitem_subject": "partial head hardened rail", "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": "レール継目部で生じる輪重変動に関する一考察", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "レール継目部で生じる輪重変動に関する一考察"}, {"subitem_title": "レール継目部で生じる輪重変動に関する一考察", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "470"], "permalink_uri": "http://hdl.handle.net/10191/26518", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-03-19"}, "publish_date": "2014-03-19", "publish_status": "0", "recid": "3251", "relation": {}, "relation_version_is_last": true, "title": ["レール継目部で生じる輪重変動に関する一考察"], "weko_shared_id": null}
