The influence of fluid force on structural motion was modeled using an added-mass matrix. This matrix was then transformed into the space composed of the eigenmodes of the hexagonal bars without added mass and used for eigenvalue analysis of the entire bar-group structure. This method reduced the computational time needed for practical added-mass matrix calculation and the eigenvalue analysis. It was shown that the proposed method yielded almost the same eigenvalues as the conventional method conducted in standard physical space. Added-mass models for use in impact- vibration analysis were investigated using the proposed method. Comparing the results calculated using the proposed method with those calculated using concentrated added mass, which is a simplified model, showed that the latter can be used for a rough response calculation, while the precise calculation requires the added-mass matrix method.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1299/jsmec1993.39.11"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1340-8062", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Toshihiko Horiuchi", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Impact vibration analysis of group of hexagonal bars immersed in liquid", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Impact vibration analysis of group of hexagonal bars immersed in liquid", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5135", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5135", "relation": {}, "relation_version_is_last": true, "title": ["Impact vibration analysis of group of hexagonal bars immersed in liquid"], "weko_shared_id": -1}
