Rotating Cam and Knife Edge Follower Mechanism Optimisation from Cam Curvature Constraints

Abstract:

The work presents an optimisation method for the rotating cam and knife edge follower mechanism using optimisation restraints required to the cam curvature radius when the follower motion law is provided. Imposing a constraint to the cam curvature radius implies a connection between the constructive mechanism parameters. The optimisation condition is plotted in the plane of constructive parameters and a closed curve corresponds to the case of a law of motion with continuous acceleration. If the “characteristic point” is placed outside this region, automatically conducts to fulfilled condition, for any mechanism’s position. For an analytical study, in the present work, the restraint of strictly positive cam curvature radius was imposed.
