However if you wish to study the effects of bolt pretension on the modal characteristics of a model, you can run a pre-stressed modal analysis. The bolt pretension is simulated in the preceding static analysis and you can use pre-stress from static analysis in the modal analysis which will give the modal characteristics based on the bolt pretension.<\/p>\n","protected":false},"template":"","class_list":["post-162231","topic","type-topic","status-publish","hentry","topic-tag-17-2","topic-tag-mechanical","topic-tag-modal-harmonic-response","topic-tag-structural-dynamics","topic-tag-structural-mechanics"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_wp_page_template":["default"],"_bbp_forum_id":["27792"],"_bbp_last_active_time":["1-24-2023  20:20:04"],"_bbp_author_ip":["23.56.168.180"],"_btv_view_count":["7123"],"siebel_km_number":["2048712"],"product_version":["17.2"],"km_published_date":["2017-03-16T13:08:18.000Z"],"family":["Structural Mechanics"],"application_name":["Mechanical"]},"test":"articlesansys-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/162231","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/topics\/162231\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/knowledge\/wp-json\/wp\/v2\/media?parent=162231"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
