The computation of three‐dimensional rolling contact with dry friction

Abstract

Abstract In this paper the computer code Duvorol, dealing with the computation of three‐dimensional rolling contact with dry friction, is described. It is based on the variational principle of Duvaut and Lions for dry friction, which leads to an incremental theory. The relevant properties of Duvorol are: Generality. All half‐space steady‐state rolling contact problems with Hertzian normal contact can be treated. Reliability. The total tangential force is always found with reasonable accuracy by a standard discretization. Speed. On an IBM 370/158 the calculation of a case then takes only several seconds.
