I have modelled a Linear feed drive system , since the linear roller bearing translates in axial direction The stiffness of the bearings are always directed along the line containing the point of contact of balls . Since these points move as the bearing moves stiffness cant be defined by a longitudinal spring that is only connect to nodes which elongates as bearings moves , the stiffness should be consistent as the system moves . What is the best way to do that in ansys? I see an option in solid works called flat parallel faces .
This picture titled (spring) shows a spring between the bearing the guide , as the bearing moves the spring elongates . I do not want this I want the spring to move as the bearing moves to maintain the same normal stiffness.
