A GVT is often the first feedback obtained concerning the dynamic properties of a new aircraft and the first chance to evaluate the FE-model that has been used during the development. After the GVT, the eigenfrequencies and mode shapes are evaluated and this data has been be used to update the FE-model such that it better represents the dynamic properties of the test object. The paper describes a series of model update procedures made on an FE-model, used for global analyses, such as flutter and load distribution, of a Gripen E test aircraft as well as FE-models of external stores and pylons.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.researchgate.net\/publication\/334030255_FE-model_update_after_GVT_of_a_Gripen_E_test_aircraft?enrichId=rgreq-94dc6020327dae5c89c227870a34aa4e-XXX&amp;enrichSource=Y292ZXJQYWdlOzMzNDAzMDI1NTtBUzo3NzM5NTQwMzc4OTEwNzRAMTU2MTUzNjQzMDY4MA%3D%3D&amp;el=1_x_2&amp;_esc=publicationCoverPdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Erik Holmberg<\/b><\/p>\n<p>DOI Number: N\/A<\/p>\n<p>Conference number: IFASD-2019-040<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2447,2433],"tags":[2288,2855,2854,807],"class_list":["post-18833","post","type-post","status-publish","format-standard","hentry","category-ground-vibration-testing","category-1-ifasd-2019","tag-finite-element-method","tag-ground-vibration-test","tag-model-update","tag-optimization","category-2447","category-2433","description-off"],"_links":{"self":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18833","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/comments?post=18833"}],"version-history":[{"count":2,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18833\/revisions"}],"predecessor-version":[{"id":18844,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/posts\/18833\/revisions\/18844"}],"wp:attachment":[{"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/media?parent=18833"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/categories?post=18833"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/aerospacerepository.org\/index.php\/wp-json\/wp\/v2\/tags?post=18833"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
