Pads are on shoes that pivot about one end and are actuated by a piston at the other end. A fairly accurate simulation of this design would be to put the pads on shoes and use a joint on one end to create the pivot and a force on the other end to push the pad against the drum.&nbsp;&lt;\/p&gt;&lt;p&gt;Your model has pads connected to ground by a Translational Joint which creates a slightly different motion than pivoting the pads about one end. Your model has no shoe so the pad are defined as either Rigid or Deformable.&nbsp; Which one did you choose?&nbsp; Each one introduces some error relative to modeling the shoe.&lt;\/p&gt;&lt;p&gt;Pads conduct heat to the shoe so it is inaccurate to have convection or radiation heat transfer from the inner pad face.&lt;\/p&gt;&lt;p&gt;It&rsquo;s fine to make an initial model that idealizes the mechanism to make a model that is quicker and easier to simulate. Just be aware that a real brakedrum is more complicated than that.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-387435","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"acf":[],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/387435","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":1,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/387435\/revisions"}],"predecessor-version":[{"id":387436,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/replies\/387435\/revisions\/387436"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=387435"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
