The stiffness for the front bearing is 293760 N\/mm and the rear bearing stiffness is 21600 N\/mm. I used equations for triple and double bearing arrangements to calculate overall stiffness. There is a force on the front of the model. For the K11, K22, K12, K21 variables I just input the stiffness values into K11 and K22. I got a deflection which makes sense to me and when I tried to put values into K12 and K21 my model would not run. With K11 and K22 only I get a warning stating &#8220;not enough constraints, MAY lead to errors or warnings&#8221;, my results are shown below. if possible can someone take a look at my file?<\/p>\n<p><\/p>\n<p>Model with Force<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/ccdd6aba-8f9a-466f-be31-a970004de685\/10ae9a49-10a4-4681-b9ba-a985005c9338_force.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/ccdd6aba-8f9a-466f-be31-a970004de685\/d8518d0b-d022-45c2-b28f-a98500602678_bearings.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>Spring Settings: K11 and K22 able to run simulation<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/ccdd6aba-8f9a-466f-be31-a970004de685\/a35f4f11-1d56-44b6-9a8c-a985006152c8_spring-settings.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>Simulation Results: 0.019 mm Deflection<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/ccdd6aba-8f9a-466f-be31-a970004de685\/9d7bf5ea-724f-4bd0-a378-a9850060ea98_results.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>&nbsp;Thank you<\/p>\n","protected":false},"template":"","class_list":["post-31124","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3296"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["2330"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31124"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","159237","160038","169537"],"_bbp_voice_count":["4"],"_bbp_reply_count":["3"],"_bbp_last_reply_id":["139168"],"_bbp_last_active_id":["139168"],"_bbp_last_active_time":["2021-01-18 13:55:25"]},"test":"env159"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31124","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\/31124\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31124"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
