Analysis of the Contact Pressure between Cams and Roller Followers in Assembled Camshafts

摘要

This work presents the results of a simulation using the Finite Elements Method (FEM) to study the contact pressure between cams and followers in assembled camshafts. The geometry was chosen based on an iron casting camshaft from a commercial car in order to have a base to ensure that the assembled camshaft is a great solution to increase the performance and to reduce weight. Surfaces that are in contact with high levels of contact pressure can increase the wear and reduce the lifetime of the components. In contact stress analysis, the most critical modeling consideration is to choose the ideal meshing, so, as a preparatory step we summarized with some simulations, defined an acceptable model to run 3D finite elements analysis and calculated the contact pressure.
