Untersuchung des Einflusses der Oberflächentopografie auf EHD-Kontakte mittels FE-Simulation

Abstract

Surface topography has a strong influence on friction in lubricated sealing contacts. In this context, FE contact simulations of measured representative surface sections are presented and compared with the wellknown Greenwood-Williamson contact model. Based on the FE simulation, the flow factors for the deformed gap topography are determined. This enables the consideration of real surface topography in EHD simulations of engineering parts.
