To achieve this, a harmonic load exciting the pinned-pinned resonance mode is considered, and a functional which derives a steady-state solution is formulated by time average of the Lagrangian. In the theoretical study, the nonlinearity is introduced in the rotational stiffness at each sleeper support. Based on the variations of the functional, the sensitivity of the above relationship to the load amplitude is revealed. Furthermore, through numerical analyses, validity of the theory is proved.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "41654", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Akutsu, Tomohiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "41655", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Koro, Kazuhiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "41656", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Abe, Kazuhisa"}]}]}, "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)2013 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": "阿久津, 友宏"}], "nameIdentifiers": [{"nameIdentifier": "41651", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "紅露, 一寛"}], "nameIdentifiers": [{"nameIdentifier": "41652", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "阿部, 和久"}], "nameIdentifiers": [{"nameIdentifier": "41653", "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": "17_105-112.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "17_105-112.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3246/files/17_105-112.pdf"}, "version_id": "ed3a8e69-e4fa-42d5-93b5-4840c07da06b"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "continuous welded rail", "subitem_subject_scheme": "Other"}, {"subitem_subject": "axial stress", "subitem_subject_scheme": "Other"}, {"subitem_subject": "resonant frequency", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mechanical nonlinearity", "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": "軌道の非線形力学特性が共振周波数・レール軸力関係に及ぼす影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "軌道の非線形力学特性が共振周波数・レール軸力関係に及ぼす影響"}, {"subitem_title": "軌道の非線形力学特性が共振周波数・レール軸力関係に及ぼす影響", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "470"], "permalink_uri": "http://hdl.handle.net/10191/31132", "pubdate": {"attribute_name": "公開日", "attribute_value": "2014-12-17"}, "publish_date": "2014-12-17", "publish_status": "0", "recid": "3246", "relation": {}, "relation_version_is_last": true, "title": ["軌道の非線形力学特性が共振周波数・レール軸力関係に及ぼす影響"], "weko_shared_id": null}
