A dynamics model was created to represent mechanism for smashing bamboo grass stems by circulating unit's teeth, and putting force onto grass was estimated during the operation. The operation unit was needed to force 2.19kN and it was more than 7.65kN per square meter onto obstacles such as vegetation, in order to operate site-preparation during moving by pushing forward at the front-end of a vehicle. The vehicle for site-preparation was estimated to be more than 4,000kg for the weight to balance the operation and moving in the forest. Operation efficiency on a slope was calculated and mowing operation on only descending direction was suitable when the inclination is steeper than 10 degrees.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54239","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NITAMI, Toshio"}]},{"nameIdentifiers":[{"nameIdentifier":"54240","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IGARASHI, Yuji"}]},{"nameIdentifiers":[{"nameIdentifier":"54241","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHMURA, Kazuya"}]},{"nameIdentifiers":[{"nameIdentifier":"54242","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OIKAWA, Ryouitirou"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科附属科学の森教育研究センター秩父演習林"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属科学の森教育研究センター研究部"},{"subitem_text_value":"及川自動車株式会社"},{"subitem_text_value":"University Forest in Chichibu, University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Research Division, University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Oikawa Motors Co., Ltd."}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"仁多見, 俊夫"}],"nameIdentifiers":[{"nameIdentifier":"54235","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"五十嵐, 勇治"}],"nameIdentifiers":[{"nameIdentifier":"54236","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大村, 和也"}],"nameIdentifiers":[{"nameIdentifier":"54237","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"及川, 良一郎"}],"nameIdentifiers":[{"nameIdentifier":"54238","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh105001.pdf","filesize":[{"value":"884.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh105001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25353/files/esrh105001.pdf"},"version_id":"d7453b6d-4434-4297-86aa-9c15e43b0c0e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地拵え","subitem_subject_scheme":"Other"},{"subitem_subject":"下刈り","subitem_subject_scheme":"Other"},{"subitem_subject":"フレールモア","subitem_subject_scheme":"Other"},{"subitem_subject":"車両","subitem_subject_scheme":"Other"},{"subitem_subject":"作業条件","subitem_subject_scheme":"Other"},{"subitem_subject":"site-preparation","subitem_subject_scheme":"Other"},{"subitem_subject":"bush-cleaning","subitem_subject_scheme":"Other"},{"subitem_subject":"frail-mower","subitem_subject_scheme":"Other"},{"subitem_subject":"vehicle","subitem_subject_scheme":"Other"},{"subitem_subject":"operational condition","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"フレールモア式地拵下刈車両の作業条件と適正質量","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"フレールモア式地拵下刈車両の作業条件と適正質量"}]},"item_type_id":"4","owner":"1","path":["2532","2531"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25353","relation_version_is_last":true,"title":["フレールモア式地拵下刈車両の作業条件と適正質量"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.634875+00:00"}
