Abstract

A cam is a mechanical device used to transmit motion to a follower by direct contact. In this study a cam and follower mechanism is analyzed. The proposed cam can be used for controlling valve and also on motor car camshafts to operate the engine valves. The dynamic analysis presents follower displacement driven by a cam rotating at a uniform angular velocity. There is a clearance between the follower and the guide. The mechanism is analyzed using computer simulations taking into account the impact and the friction between the flat-faced follower and the guide. Four different follower guide's clearances have been used in the simulations and the Largest Lyapunov Exponents have been calculated. An experimental set up is developed to capture the general planar motion of the cam and follower. The measures of the cam and the follower positions are obtained through high-resolution optical encoders (markers) mounted on the cam and follower shaft. The effect of guide clearance is investigated for different angular velocities of the cam. The largest Lyapunov exponents for the simulated and experimental data are analyzed and selected.
