Analytic and numerical results of a disc cam bending with a roller follower

Abstract

The bending deflection of a disc cam with a roller follower was analyzed by using constant angular velocity of the cam. The objective of this paper was to study the effect of the contact load on the bending deflection of the cam profile. Numerical simulations were carried out using SolidWorks and ANSYS Ver. 19.2 package based on finite element analysis. SolidWorks was used to determine the dynamic response of the follower, while the bending deflection of the cam profile has been investigated using ANSYS package. The modal and harmonic analyses were used to find the natural frequency and the dynamic response of the bending deflection. The theory of circular plate was applied to derive the analytic solution for the bending deflection. The experiment data has been collected with an infrared camera system. The dynamic response of the follower, at the point of contact, was verified analytically and experimentally. The reduction rate for bending deflection is (73.425%) for path no. (1), (85.925%) for path no. (2), and (61.467%) for path no. (3). The harmonic amplitude peak of the point (18) on the nose (2) is bigger than the peak of the point (4) on the nose (1) because of large values for the radius of curvature of the nose (2).
