However, when using a hydraulic servomechanism for the mechanical power output stage of a control system, which employs a step input command as the control signal, a soft characteristic is required since these types of servomechanism should not incur large overshoot and/or high acceleration, especially in the mass loaded condition. For this reason, the object of this paper is to clarify the behavior of the hydraulic soft servomechanism experimentally, and to evaluate simulation accuracy and method, through a comparison of the results of experimental data and mathematical model calculation data. The experimental hydraulic soft servomechanism equipment is composed of an ordinary flow control servo valve and an actuator(cylinder), employing combined position-and velocity-feedback, which provides a rather long stroke at high speed and high accuracy with no overshoot and very small shock acceleration. From these studies, the following can be clearly understood: 1)First, system experiments were performed to accurately grasp its behavior; 2)The influence of velocity feedback, which provided circuit compensation for softening of the hard servomechanism characteristic, was confirmed; i.e. the occurence of overshoot ΔY and the amount of maximum shock acceleration G, were dependent upon the amount of velocity feedback, from the hard characteristic zone to the soft zone; 3)The influence of three parameters(Rf:position, velocity feedback ratio, CL:load factor, γ:time constant of servo valve) to the control system, was confirmed; 4)From the results of the comparison of all experiments and the simulation, it was confirmed that both results coincided, and it was clear that applicability of the mathematical model and simulation study utilization were excellent.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0483000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-483","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所計測部"},{"subitem_text_value":"宇宙開発事業団"},{"subitem_text_value":"元・上智大学"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Instrumentation and Control Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan(NASDA)"},{"subitem_text_language":"en","subitem_text_value":"Former Sophia University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"池谷, 光栄"}],"nameIdentifiers":[{"nameIdentifier":"470983","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶井, 誠"}],"nameIdentifiers":[{"nameIdentifier":"470984","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"IKEYA, Mitsuei","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"470985","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KAJII, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"470986","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":"2020-01-29"}],"displaytype":"detail","filename":"naltr00483.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00483.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44736/files/naltr00483.pdf"},"version_id":"568b8e0d-c0f7-484e-8004-4e956a215919"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"油圧式ソフトサーボ機構の実験的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"油圧式ソフトサーボ機構の実験的研究"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44736","relation_version_is_last":true,"title":["油圧式ソフトサーボ機構の実験的研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:51:43.663559+00:00"}
