    Reaction moment in bushing analysis

    Ryan Noble

      I'm looking into the possibility of designing some suspension bushings with the help of Simulation Premium, but am having trouble getting some key information from my analysis.

       

      Basically, I have an inner and outer ring that are connected via a bonded rubber. I need to be able to apply a 1° rotation normal to the bushing axis, then get the torque required to drive the 1° rotation. When I run the analysis (which has to be non-linear due to the rubber material), and try to "List Result Force", I don't have the option for "Free body force" which I'm assuming is what I would need in order to captuer the reaction moment.

       

      I've attached a .pdf with some visuals that will show you what I'm trying to do.

       

      Is there something I'm doing incorrectly? Is this something simulation can't do?
