Select a particular shape for cam profile can play an important role in reduction of energy in automobile motors. Engineers try to reduce this dissipated energy to improve the motor operation. This paper obtains nonlinear governing equation of disk cam follower motion and optimizes it with calculus of variation. Because of optimum cam profile, also, maximum acceleration of the follower is decreased. Finally, we solve it analytically by means of Homotopy analysis method and numerical results have been reported to prove the soundness of the analytical method.
