Effect of Eccentricity on the Nonlinear Dynamic Behavior of a Cam and Follower Mechanism With Clearance

This study evaluate the relationship between flat-faced follower’s offset and Lyapunov exponent. The nonlinear dynamic behavior has been investigated based Lyapunov exponent value. Two types of follower offset such as (e = 10, and 20 mm) has been examined from each side of the cam radial line. The simulation process has been done by using solidwork program. The power spectrum of Fast Fourier Transform and phase plane have been examined the follower non-periodicity during follower motion. The optimum follower offset that would minimize Lyapunov exponent is determined. The system with follower guide’s clearance C = 2 mm and e = 20 mm has larger Lyapunov exponent than the others at cam rotational speed N = 1200 rpm. The signal of follower motion is processed by using MATLAB program.
