You just import this geometry into the Geometry cell, then in the Model, create the joints and springs and import the input displacement as a joint load on the translational joint that connects the road body to ground. When you Solve, you will get a Transient solution and you can plot the displacement or acceleration of the car body and the wheel body.<br \/>\nYou don&#8217;t need a Fixed Support. The translational joint between ground and the road body, along with the input displacement load is equivalent to the fixed support.<\/p>\n","protected":false},"template":"","class_list":["post-183202","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/183202","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/reply"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/183202\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=183202"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
