Especially a problem of the soil-wheel interaction was focused in this study. An analyzing system of soil deformation, one of stress distribution in the soil and data processing systems have been developed as subsystems of the verifying system. An elasto-plastic Finite Element Method and a soil bin experimental apparatus also were developed. The concept of database plays important role on the verifying system. Soil deformation beneath the wheel could be observed at the rolling motion of the wheel through the side wall of the soil bin. Displacement vectors of soil particles and isobar distributions were discussed. Typical distribution patterns of each kind of strain were clarified in initial sinkage and in rolling stages. Displacement vectors in the neighbor of the wheel increased rapidly at the immediate after an appearance of the maximum traction. Stress analysis was able to carry out by the data of strain distributions and an elasto-plastic constitutive equation based on the Subloading Surface Model. This system applied to the experiment results of the wheel traveling with 26% slip. Adatabase was caonstructed by accumulating these experimental data and total analyzing system was developed. This system was extended to a comparing system with the analytical results by the FEM.", "subitem_description_type": "Other"}, {"subitem_description": "未公開：P.35以降(別刷論文のため)", "subitem_description_type": "Other"}, {"subitem_description": "研究報告書", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "上野正実"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/13567"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "NCID", "subitem_1522646572813": "BA35583656"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueDates": {"bibliographicIssueDate": "1995-02", "bibliographicIssueDateType": "Issued"}}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "research report", "resourceuri": "http://purl.org/coar/resource_type/c_18ws"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "HDL", "subitem_1522306436033": "http://hdl.handle.net/20.500.12000/3763"}}, {"subitem_1522306287251": {"subitem_1522306382014": "HDL", "subitem_1522306436033": "http://hdl.handle.net/20.500.12000/3766"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "download_preview_message": "", "file_order": 0, "filename": "05660297.pdf", "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2005068/files/05660297.pdf"}, "version_id": "668d7204-f68a-4bab-aea1-82365374dbc9"}]}, "item_title": "農業機械分野における有限要素解析の検証システムに関する研究", "item_type_id": "15", "owner": "1", "path": ["1642838403123", "1642838407312"], "permalink_uri": "http://hdl.handle.net/20.500.12000/13567", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2009-12-02"}, "publish_date": "2009-12-02", "publish_status": "0", "recid": "2005068", "relation": {}, "relation_version_is_last": true, "title": ["農業機械分野における有限要素解析の検証システムに関する研究"], "weko_shared_id": -1}
