The support load was also increased to 10 tons. The frame stand (4m × 2m) is equipped with four fluid-levitation horizontal vibration reduction devices. Previously, differential fluids were limited to easily manageable \"air,\" but for future large-capacity applications, \"water\" was also compared. The results showed that there was no significant difference in vibration reduction performance, yielding good results comparable to related studies. A unique finding was that \"water\" made it more difficult to separate from the sliding surface, which differentiates it from air. The measurement data and images obtained from this experiment are available.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"データ取得：2019年","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"Data acquisition period : 2019","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"お問い合わせ：asebi@bosai.go.jp","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"inquiry： asebi@bosai.go.jp","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"防災科学技術研究所"},{"subitem_1522300295150":"en","subitem_1522300316516":"National Research Institute for Earth Science and Disaster Resilience"}]},"item_1617186660861":{"attribute_name":"Date","attribute_value_mlt":[{"subitem_1522300695726":"Issued","subitem_1522300722591":"2021"}]},"item_1617186783814":{"attribute_name":"識別子","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"10.17598/NIED.0020-E201902"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"dataset","resourceuri":"http://purl.org/coar/resource_type/c_ddb1"}]},"item_1617353299429":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_1522306207484":"isIdenticalTo","subitem_1522306287251":{"subitem_1522306382014":"URI","subitem_1522306436033":"https://asebi.bosai.go.jp/"},"subitem_1523320863692":[{"subitem_1523320867455":"en","subitem_1523320909613":"LOGIN Page for Registered Users"}]}]},"item_title":"フレーム架台振動低減装置の性能確認実験","item_type_id":"40006","owner":"7","path":["1749778844647"],"publish_date":"2025-06-19","publish_status":"0","recid":"7227","relation_version_is_last":true,"title":["フレーム架台振動低減装置の性能確認実験"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2025-06-23T05:39:18.988594+00:00"}
