I want to simulate that shaft just to prove that my shaft wont break. So i simulated that shaft with a 35Nm torque, and an axial force of 130N, put the problem is im only getting a 24MPa Von Mises with those forces and that means my safety factor acording to the simulation would be something like 20. Dont know if my boundary conditions are alright or if the result is fine and i just cant understand that big of an diference between the choosen safety factor and the simlated one.<\/p>\n<p><\/p>\n<p>Boundarie Condition: I aplied fixed suport on the part that the shaft in insite the worm gearbox, torque on all the shaft and axial force on the part where is gona be an tagencial force acting .<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/01dc9b6d-1acd-40eb-8412-a98b0177531e\/871f250d-0697-424a-9e02-a9b700ba7866_capturar2.jpg?width=690&amp;upscale=false\" alt=\"boundarie condition\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/01dc9b6d-1acd-40eb-8412-a98b0177531e\/540e8371-b5fd-4abb-a566-a9b700ba9193_capturar.jpg?width=690&amp;upscale=false\" alt=\"results\"><\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"template":"","class_list":["post-32161","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["4333"],"_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":["3532"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["32161"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","160042"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["72484"],"_bbp_last_active_id":["72484"],"_bbp_last_active_time":["2018-12-15 17:31:00"]},"test":"salocin155"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/32161","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\/32161\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=32161"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
