Abstract
This paper proposes an approach to optimal design of cam curves. In the approach, cam curve is described with a uniform B-spline curve and then the values of B-spline control points are optimized with the Complex Method according to the utilization purpose. The algorithm is simple and the programming is easy since it only needs to compute the performance value but require no the gradient of the index function in optimization calculation. Some examples of designing cam curve to control the residual vibration with indexing cam mechanism are shown. The outcomes sufficiently illustrate the effectiveness of the approach.
