Effect of the Impact Coefficient of Restitution on the Nonlinear Dynamics Phenomenon of Flat-Faced Follower With Polydyne Cam Mechanism With Clearance

Abstract

The effect of impact coefficient of restitution on the nonlinear response of the follower is investigated at different follower guides’ clearances, different cam speeds and different followers’ offsets. The impact between the cam and the follower and between the follower and its guides are considered in the presence of coefficient of restitution and follower offset. The chaotic phenomenon of the follower due to the impact coefficient of restitution is detected by using phase-plane diagram. The numerical simulation of the nonlinear response of the follower is simulated using SolidWorks program. The chaotic phenomenon in cam follower system is increased with the increasing of impact coefficient of restitution value in which the potential energy of the follower has been decreased in the presence of follower offset. The chaotic motion of the follower response is occurred due to the increase in cam speeds, follower’s offsets, follower guides’ clearances and impact coefficient of restitution.
