A disc cam and roller follower mechanism are discussed and analyzed for bending deflection of the cam profile and dynamic response of the follower.  The spring and damper are applied at the end point of the follower stem. The objective of this paper is to study the influence of maximum contact pressure on the bending deflection of the cam profile. Numerical simulation is carried out using SolidWorks Software to simulate the follower displacement, velocity and acceleration. The area of contact can be assumed to be semi-ellipsoid in SolidWorks software with a rectangular contact zone of half-width (b) and length (L) (contact between two parallel cylinders). Finite element analysis is considered taking into account the use of ANSYS package to calculate the bending deflection.  Linear elastic isotropic model is used to calculate the bending deflection of cam profile. Element (PLANE 42) is assigned to create the mesh generation of finite element analysis. This element is defined by four nodes which is having two degrees of freedom at each node: (translations in the nodal x, y directions). The experiment setup has been done through an infrared camera device. The dynamic response of the follower are checked and verified numerically and experimentally at the point of contact. The bending deflection of point (18) is bigger than the bending deflection of point (4) because of the bigness of radius of curvature of nose (2).

DSCC2020 - Virtual Conference

Supporting the need among researchers worldwide for additional online and multimedia content, ASME now offers the ASME Conference Video Collection. This platform will collect and provide long-term access to conference presentation videos, encompassing all technology areas within ASME's technical conference and events program. About 30,000-40,000 engineers across all mechanical engineering and related disciplines participate in ASME conferences each year. This includes authors of approximately 6,000 to 8,000 technical papers published by ASME, the majority of whom also submit video presentations for our virtual conferences. The video collection will be available as an add-on to existing product packages or as a separate subscription.
