Abstract
Summary A computer-based optimal design tool which can be used to design and optimize cams of different cam and follower configurations, namely the knife, roller, flat and swing followers, is presented. The designer may choose to optimize the cams on the basis of radius of the cam base circle, the width of the cam, the follower roller radius and its offset, and so on. The method is based on an exploratory search method known as the Monte Carlo method in which random points are generated over the range of all the variables, and the feasible solution found for a multi-objective problem is tested against the Pareto optimality criteria. The method is advantageous because it can be used to solve all classes of non-linear problems and it does not require any specific strategy point to initiate the optimization process. In a selected case study for a cam with translating roller follower, the volume of material has been reduced by 35% compared with earlier work by Fenton.
