One of the major applications of cam mechanism is valve actuation of Internal Combustion (IC) engines. This work deals with the follower response determination for a given prescribed cam motion for single DOF cam mechanism. Here follower response by two methods are presented first one is using Johnson's numerical method analytically obtained the dynamic response. In the second method transient dynamic analysis is carried out using FEM. Here each method is carried out considering two types of cam motions, parabolic motion and cycloidal motion. The responses of both methods are yielding good agreement.
