FE Analysis of Tangent Cam for Different Positions of the Roller Follower
Journal Title: REST Journal on Emerging trends in Modelling and Manufacturing - Year 2015, Vol 1, Issue 1
Abstract
The cam and follower assembly is been used to convert rotating motion into reciprocating or oscillating motion. The cam is made in contact with the follower at all time by the use of retaining springs. To give a reciprocating action, when the follower is lifted to certain height by the cam, there is generation of the stresses. Here these stresses are investigated by finite element analysis of the tangent cam at all possible positions where follower is being lifted. A 10 N load is applied at the line contact of the cam and the follower. When ‘Jump phenomenon’ has been taken place, the follower reciprocates rigorously giving higher impact at the points where the cam lifted the follower. A tangent cam has been modeled in Solidworks 2014 edition. Six different positions of the follower are considered. The follower is in line contact of the cam. A finite element model is made in ANSYS v15.0. The model is meshed using SOLID186 elements. Von mises stresses has been found out and plotted at all the positions comparatively. The vector plot has been used to get the effect these stresses on the material of the cam and depth of the effect due the loading.
