APPLICATION OF BÉZIER CURVES IN THE DESIGN AND OPTIMIZATION OF CAMS FOR HIGH SPEED

Abstract:

In this article the comparison of the dynamic response of a cam follower system is made between several laws of motion. The laws that are compared are the study of a hypothesis that is intended to validate denominated Bezier Degree 15, against standard laws used in the design of cams like polinomial law 3-4-5, polinomial law 4-5-6-7, the cycloidal law and the Bezier in stages. For this purpose three different dynamic models are used: a model of a degree of freedom that supports the residual vibration, the model that considers the flywheel to verify torsional vibration and a model of two degrees of freedom to identify the takeoff of the follower. Once the comparative advantages are demonstrated, the cam design and its subsequent construction are carried out. Then a study of the generated noise is made to support the proposal presented.
