Abstract

Surface roughness plays an important role in ElastoHydrodynamically Lubricated contacts, a role which is currently only partially understood. Recent work on waviness in EHL line contacts has shown and quantified the elastic deformation of the waviness inside the contact as a function of a single dimensionless parameter. In the present paper this work is extended to the circular contact problem. First it is shown that the amplitude reduction of an isotropic harmonic pattern can also be described as a function of a single dimensionless parameter. Subsequently, the effects of anisotropy are investigated varying from purely transverse to purely longitudinal. It is shown that one can create a single curve for the case varying from isotropic to longitudinal, and another for the case varying from isotropic to transverse. Both curves can be combined in a single formula.
