An Optimum Design of Cam Mechanisms with Roller Follower for Combined Effect of Impact and High Contact Loads

The problem in the design of a cam is the analyzing of the mechanisms and dynamic forces that effect on the family of parametric polynomials for describing the motion curve. In present method, two ways have been taken for optimization of the cam size, first the high dynamic loading (such that impact...
