The problem here regarding the transient analysis first I have done quarter car model using MATLAB using a bump to obtain the acceleration from the suspension system second I have my fixed Support in the place of the four wheels of the chassis done in the modal analysis third I put the Acceleration obtained from MATLAB on the two front wheels of the chassis and the two rear wheel is fixed and I have done it using Base excitation. The problem here is the values of the Stress is too large. Is the problem regarding the settings of Ansys specifically The acceleration settings regarding the The base Excitation and absolute result Or I have read about damping ,stiffness, mass coefficient so applying them will make difference in the values of stresses . or another thing should be taken into consideration<\/p>\n<p>It will be helpful is someone could help As this my Bachelor Project.<\/p>\n<p>Thanks in Advance.<\/p>\n","protected":false},"template":"","class_list":["post-159776","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_author_ip":[""],"_bbp_old_reply_author_name_id":["Anonymous"],"_bbp_old_is_reply_anonymous_id":["false"],"_btv_view_count":["557"],"_bbp_likes_count":["0"],"_bbp_subscription":["241256"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["159776"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","201926"],"_bbp_voice_count":["2"],"_bbp_reply_count":["22"],"_bbp_last_reply_id":["183210"],"_bbp_last_active_id":["183210"],"_bbp_last_active_time":["2021-06-25 20:34:46"]},"test":"bolaamirhalim123gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/159776","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\/159776\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=159776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
