Design General Cam Profiles Based on Finite Element Method

This paper presents a general framework to design cam profile using the finite element method from given displacements of follower. The arbitrarily complex is described by Lagrangian elements, which are formed connectivity nodes. In order obtain desired profile, penalty-type functional that enforces prescribed displacement follower proposed. Additionally, in ensure convexity functional, numerical stabilization scheme used. nodal positions then obtained solving nonlinear system equations resulting minimizing total functional. geometrical accuracy can be controlled number elements. A case study considered illustrate flexibility, accuracy, and robustness proposed approach.
