About Cam-Follower Connections with Liftoff
You can specify whether the two rigid bodies in your cam-follower connection remain in contact during a dragging operation or a motion run.
• If you select Enable liftoff on the Cam-Follower Connection Definition dialog box, the two cams are allowed to separate and collide during a dragging operation or an analysis run. The cams do not interpenetrate if they collide.
• If you enable liftoff, you can also define a coefficient of restitution for your cam-follower connection. This value determines the energy loss due to the impact when cams collide after separating.
• If you do not select Enable liftoff, the two cams remain in contact.
