For this purpose, firstly the Tip Ball type indenter\u0027s vibratory system is considered and concluded with the vibratory model of one degree of freedom by the theory of vibration, and shown that in this model, if the ratio of natural period of an indenter to the duration time of impact is very small, the movement of a holding shaft is preportional to the impact force. Therefore the energy stored in a holding shaft during impact can be calculated easily, being equal to the total of this energy and the energy of the contact areas of an indenting sphere and a material using Hertz\u0027s Contact Law to the rebound energy of an indenter. The equation of the rebound energy of a Tip Ball type indenter is shown. Next, the results of experiments with several Tip Ball type indenters are given and clarify quantitatively that measured values are consistent with the analyzed values within an accuracy of about ±5% and the influences of a holding shaft are larger as the falling height becomes higher, and the material becomes softer. Finally, the above mentioned points of that influence are confirmed for the Hardness Number by the experiment using the indenter of the D type Shore Hardness Testing Machine.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "44776", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ishibashi, Tatsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "44777", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Shimoda, Shigeru"}]}]}, "item_5_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "日本機械学会"}]}, "item_5_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "日本機械学会"}]}, "item_5_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN0018742X", "subitem_source_identifier_type": "NCID"}]}, "item_5_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03875008", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "石橋, 達弥"}], "nameIdentifiers": [{"nameIdentifier": "44774", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "下田, 茂"}], "nameIdentifiers": [{"nameIdentifier": "44775", "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": "3_0004.pdf", "filesize": [{"value": "781.6 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 781600.0, "url": {"label": "3_0004.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/3700/files/3_0004.pdf"}, "version_id": "c3e6aeb8-f977-4e5f-80fc-f20b46aad87d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Material Testing", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rebound Hardness", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Tip Ball Type Indenter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Holding Shaft of an Indenting Sphere", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Vibratory Model of One Degree of Freedom", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rebound Energy", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hertz\u0027s Contact Law", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hardness Number", "subitem_subject_scheme": "Other"}, {"subitem_subject": "D Type Shore Hardness Testing Machine", "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": "反発硬さ関係式に及ぼす圧子球保持軸部の影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "反発硬さ関係式に及ぼす圧子球保持軸部の影響"}, {"subitem_title": "反発硬さ関係式に及ぼす圧子球保持軸部の影響", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["454", "425"], "permalink_uri": "http://hdl.handle.net/10191/1770", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-05-10"}, "publish_date": "2007-05-10", "publish_status": "0", "recid": "3700", "relation": {}, "relation_version_is_last": true, "title": ["反発硬さ関係式に及ぼす圧子球保持軸部の影響"], "weko_shared_id": null}
