Analysis about the Influence of the Damping Structure on the Mechanical Property of Roller

Abstract

Abstract. The falling of wear layer on the surface of roller is a main form of roller failure. Based on the typical structure of normal roller and bionic coupling theory of structure and material, a coupling roller with strips on the surface of damping layer is designed. To study the mechanical property of the coupling roller, several numerical computations are carried out depending on the boundary condition and force loader of the working roller. The results prove that this kind of coupling roller has a better performance in reducing the possibility of crack generation by decreasing the difference of stress and strain gradient in the contact area of damping layer and wear layer and the size of the strips can also affect the ability of relatively soft damping layer material to reduce the stress impact.
