Replacing the Remaining Redundancies with Bushings

Next, you replace the remaining redundant mates with bushings.

1. Click Motion Study Properties (MotionManager toolbar).
2. Under Motion Analysis, click Replace redundant mates with bushings and click .
3. Click Calculate (MotionManager toolbar).
   The number of redundancies reduces to 0, removing the remaining redundant constraints.

   The modified local mate icons update to indicate replacement with automatic bushings .
4. In the MotionManager tree, expand Results .
5. Right-click Plot1<Reaction Moment1> and click Show Plot.
   

   The reaction moment has a spike at approximately 2.25 sec. This spike is expected, since the motion indicates that the piston displacement is maximum at about 2.25 sec. This spike is missed if you do not remove the redundancies.

6. Save the model.
