Hamm and J. Géminard [Amer. J. Phys. 78, 828 (2010)], a simple dynamical model of a vertically falling train of one-dimensional rigid segments impinging onto an inelastic horizontal plate in three-dimensional space was developed. The nonlinear governing equations were numerically integrated, and it was observed that the train of rigid segments fell virtually faster than a particle in freefall under gravity. We found that the maximum bend angle between successive chain links largely affects on the acceleration. The presented model reproduced the coiling spontaneously occurring in the pile, which is considered to be an aspect of the mechanism and is shown to be a consequence of the three-dimensional spiral structure that arises due to dissipative locking of segments in mid-air. As one of the mechanical aspects underpinning the apparently counterintuitive phenomena, the downward tensile force exerted by the pile was focused on.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"article ID: 044401","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"KAKENHI: 20K04294","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_9_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The Physical Society of Japan","subitem_publisher_language":"en"}]},"item_9_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.7566/JPSJ.90.044401","subitem_relation_type_select":"DOI"}}]},"item_9_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 2021 The Physical Society of Japan","subitem_rights_language":"en"}]},"item_9_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00704814","subitem_source_identifier_type":"NCID"}]},"item_9_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13474073","subitem_source_identifier_type":"EISSN"},{"subitem_source_identifier":"00319015","subitem_source_identifier_type":"PISSN"}]},"item_9_version_type_17":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Itano, Tomoaki","creatorNameLang":"en"},{"creatorName":"板野, 智昭","creatorNameLang":"ja"}],"familyNames":[{"familyName":"板野","familyNameLang":"ja"},{"familyName":"Itano","familyNameLang":"en"}],"givenNames":[{"givenName":"智昭","givenNameLang":"ja"},{"givenName":"Tomoaki","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"24078","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"30335187","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/nrid/1000030335187"},{"nameIdentifier":"0000-0002-6688-6225","nameIdentifierScheme":"ORCID iD","nameIdentifierURI":"https://orcid.org/0000-0002-6688-6225"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-12-11"}],"displaytype":"detail","filename":"KU-1100-20210415-00.pdf","filesize":[{"value":"3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://kansai-u.repo.nii.ac.jp/record/2002131/files/KU-1100-20210415-00.pdf"},"version_id":"ac90cd94-b60a-4b24-b41f-5770e99ed922"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"free falling","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ball chain","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical model","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"rigid body mechanics","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"関西大学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"A Simple Dynamical Model of a Freely Falling Train of Rigid Segments","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"A Simple Dynamical Model of a Freely Falling Train of Rigid Segments","subitem_title_language":"en"}]},"item_type_id":"9","owner":"10","path":["1591"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-12-11"},"publish_date":"2024-12-11","publish_status":"0","recid":"2002131","relation_version_is_last":true,"title":["A Simple Dynamical Model of a Freely Falling Train of Rigid Segments"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2024-12-11T06:14:19.725684+00:00"}
