Bifurcation Diagram of a Polydyne Cam with an Offset Flat-FacedFollower Mechanism

Louay S. Yousuf

 A bifurcation diagram is used to measure how high the follower detaches from the cam profile due to follower offset. Bifurcation diagram has been investigated for distinct cam angular velocities and follower offsets. There is a clearance between the follower and its guides by taking into account the friction between the cam, follower, and the two guides. The impact between the cam, follower and the two guides is occurred due to the impulse and momentum phenomenon. The bifurcation diagram is examined the nonperiodic motion for the follower. The numerical simulation has been done using SolidWorks software. Follower movement is processed experimentally through an infrared 3-D camera device with a high precision optical sensor. Nonlinear dynamic of the follower is examined in the presence of follower offset. The contact point between the cam and the follower is considered in bifurcation diagram
