I have a large shaft supported on two bearing contacts with a centralised load. I have set the stiffness values of the bearing contacts to values I&#8217;ve calculated for large spherical roller bearings (1E7 N\/mm). I have simplified the assembly all the way back to basics in order to try and determine the issue and it appears the bearing contacts are not supporting the model as expected and are allowing the shaft to move radially.<\/p>\n<p>I have a remote displacement support on one end of the shaft to stop it rotating and sliding around it&#8217;s axis.<\/p>\n<p>Please see the screenshots below. Any help would be greatly appreciated.<\/p>\n<p><span style=\"font-size: 11.0pt;font-family: 'Calibri',sans-serif\"><!-- [if gte vml 1]&gt;--><\/p>\n<p><!-- [if !vml]--><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/20-10-2023-1697795560-Bearing 1.png\" alt=\"\"><br \/><!--[endif]--><\/span><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/20-10-2023-1697795575-Bearings 2.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/20-10-2023-1697795586-Remote Displacement.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/20-10-2023-1697795603-Load.png\" alt=\"\"><\/p>\n<p>&nbsp;<\/p>\n<p>Thanks, Morgan<\/p>\n","protected":false},"template":"","class_list":["post-312498","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["296127","58821"],"_bbp_author_ip":["23.206.193.41"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["2036"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["312498"],"_bbp_forum_id":["27791"],"_bbp_engagement":["58821","296127"],"_bbp_voice_count":["2"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["312569"],"_bbp_last_active_id":["312569"],"_bbp_last_active_time":["2023-10-20 15:50:08"]},"test":"morgan-ramanauskas-2021uni-strath-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/312498","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/312498\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=312498"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
