The dynamic behavior of overhead cam mechanisms, commonly used in automotive applications, is strongly influenced by the Coulomb friction at the rocker arm pivot. In this study, a non-linear one-degree-of-freedom model of such a mechanism including Coulomb friction has been developed. An exact quasi-linear solution to the equations representing the non-linear behavior has been obtained. The effects of Coulomb friction at different cam speeds are investigated using typical parameter values. A critical examination of the simulation of the dynamic behavior of the cam mechanism by using an equivalent viscous damper to replace the Coulomb friction is made.
