“…This research was aiming to evaluate the effect of contact stress between cam and follower and also frictional losses by using the finite element analysis to improve the engine efficiency. Fang and Chen 19 investigated optimum design of cam curvatures by using genetic algorithm to optimize the control points of B-splines under the required design constraints.…”

Mathematical modeling, simulation, and optimum design of equivalent one degree-of-freedom high-speed cam mechanisms used for internal combustion engines are investigated in this study. The dynamic equation governing the dynamic behavior of a typical high-speed cam–follower system of an internal combustion engine has been simplified using dimensionless analysis method. The resulting model is then used to find the optimum cam shape to reduce the residual vibrations in the follower part of the system. The Lagrange multipliers method is utilized to minimize the sum of squared error (deviation from the cam profile) over one period under continuity and smoothness constraints.

This paper proposes a cam curve synthesis method based on classical splines. The cam curve is described by the classical spline of order 6. Corresponding equations and boundary conditions are given to satisfy the specific requirements of the cam design problem. Then, a universal computation method is given and an example to illustrate the effectiveness of the proposed method is presented. It is shown that excellent design result can be gained easily, and the designer can adjust the interpolation values of the interior knots of the spline to change the cam curve in a local influence without any violation of the specific constraints.
