Abstract

Microstructures on polymer surfaces are known to reduce friction and the
visibility of scratches. Due to the complex interaction of multiple surface areas in contact
with each other the prediction of coefficient of friction (COF) or wear is difficult and depends
on an empirical solution. This article deals with possibilities of calculating the deforming
part of friction via an analytical solution and a FE-model. In a first step the modelling of
single contacts is demonstrated. The analytical calculation based on the Hertzian contact
equations is extended regarding viscoelastic material parameters. The basic approach of
FE-modelling is explained including calibration of the material model using the software
MCalibration®. The article introduces the different procedures of simulating and modelling
COF and wear taking into account the area of contact and resulting stress distribution.
