REDUCTION OF STRESS CONCENTRATION BETWEEN PLATE CAM AND ROLLER FOLLOWER BY ROUNDING THE EDGES

This paper focuses on reduction of the stress concentration between a cam and follower by rounding the edges. A cam and its follower are designed for carrying out a simple harmonic motion. A CAD model of the flat edged cam is made with dimensions obtained from design calculations , followed by finite element analysis. Similarly, another CAD model of similar cam with rounded edges is made with the same dimensions, followed by finite element analysis. It can be found that the equivalent stress concentration is less at the rounded edges of the second model than the flat edges of the first model.
