“…It is critical to notice that there exist four constraints in the given optimization problem as indicated by equation (16). Since a third-order polynomial can only satisfy these constraints, no optimization on the cam profile is actually possible.…”

“…15 It is also well known the fact that the best valve-train system modeling and dynamic analysis of high-speed engines will increase the efficiency of ICEs. 16 The most critical system dynamics parameters of the high-speed camfollower systems are the time-wise control of the events, accelerations, and high frequency vibrations, which should be considered in the design optimization. Several techniques were investigated by Jamkhande et al 16 to control the high frequency vibratory response.…”

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.

“…The analysis of the cam will be done by using computerized engineering software such as CATIA and MATLAB. This analysis is designed so that optimization of the cam profile can be done and thus, the factor affecting the optimization of the cam can be determined [2]. The collected data will be analyzed properly so that the pattern graph of displacement, velocity, acceleration and jerk versus angle of cam rotation can be established.…”

“…Jamkhande, A. et al [6] expose the impact of different cam profile options designed using Polydyne, N-Harmonic and Bspline methods on a field problem of cam wear for high speed engine application. The authors conclude that the cam lobe designed by B-spline method gives the better results and it is the better design option.…”

This work analyses the incidence of the parameter selection of B-spline curves, used in the design of displacement and motion functions , on its degree of freedom and shape. A complete design process based on the use of non-parametric B-spline curves and the convenience of selecting the curve parameters from the point of view of its practical application is shown. In order to make easy the design and use of the displacement function, the algorithms for derivation and integration of the B-splines used are presented. Three case studies validate the proposed design process and the selection of the adequate parameters. The first case presents the design of a displacement function of a roller follower driven by a disk cam; the corresponding cam profile and its prototype are shown. The second case presents the design of the motion function corresponding to the cutting unit of a manufacturing cardboard tube machine. The third case exposes the design of the displacement function of the bar feeding mechanism in a single-spindle automatic lathe, to produce a partial thread screw of hexagonal head. Response to Reviewers: The manuscript was properly revised as pointed out, so it is now acceptable for publication. The authors would thank to the reviewers and the editor their decision.
