However, in the previous report, it was shown that the truck with forced steering mechanism can not reduce the lateral wheel force on sharp curves. This paper deals with a study of a forced steering truck with three axles that has an asymmetric steering lever. In the steering mechanism, the 1st axle in each truck, front and rear, has a larger leverage ratio than the 3rd one, because the lateral force of the leading wheelset is greater than the ones of the other wheelsets on the sharp curve. In the analysis, it is shown that the asymmetric steering mechanism is effective for the reduction of the lateral force of the leading wheelsets in both trucks on the curve sections of radius down to a certain value. For sharp curves of radius less than that, it is confirmed that the addition of self-steering ability to the forced steering truck can make the curving performance better, and it is made clear that the existence of slack affects much to the self-steering ability.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "45539", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Tanifuji, Katsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "45540", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Imata, Ryoichi"}]}]}, "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/110002382957", "subitem_relation_type_select": "URI"}}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}, {"subitem_rights": "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": "45537", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "今田, 亮一"}], "nameIdentifiers": [{"nameIdentifier": "45538", "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": "9_0147.pdf", "filesize": [{"value": "703.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 703900.0, "url": {"label": "9_0147.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3812/files/9_0147.pdf"}, "version_id": "233184f8-eb8f-4e69-9458-c47627b2451c"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Railway", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Motion Control", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Curving Performance", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Forced Steering", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Three-Axle Truck", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Asymmetric Leverage Ratio", "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": "前後に非対称な操舵てこ比を利用した鉄道台車の曲線通過", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "前後に非対称な操舵てこ比を利用した鉄道台車の曲線通過"}, {"subitem_title": "前後に非対称な操舵てこ比を利用した鉄道台車の曲線通過", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/5849", "pubdate": {"attribute_name": "公開日", "attribute_value": "2008-04-08"}, "publish_date": "2008-04-08", "publish_status": "0", "recid": "3812", "relation": {}, "relation_version_is_last": true, "title": ["前後に非対称な操舵てこ比を利用した鉄道台車の曲線通過"], "weko_shared_id": null}
