Abstract



Dwindling resources and stricter legal
requirements call for efficient machine elements and engine components.
Therefore, tribological contacts with low frictional losses are vital. This can
be achieved, for example, by applying discrete micro-textures to the surfaces
of contacting bodies in lubricated tribological systems. While this approach has
already been intensively investigated for lower loaded conformal contacts under
hydrodynamic lubrication, the application and design of surface textures for
higher loaded, non-conformal contacts under thermo-elastohydrodynamic
lubrication (TEHL) is much more controversially discussed and still under
basic research.



In this context, tribo-simulations offer the
great potential to explore the underlying basic mechanisms in terms of friction
and wear reduction and to facilitate design optimization in order to avoid
time-consuming and costly trial-and-error experiments. The aim of this
contribution was therefore to investigate the impact of different
micro-texture’s characteristics on the tribological behavior using transient 3D
TEHL simulations based upon a full-system approach. Meta-models of optimal
prognosis (MOP) and evolutionary algorithms (EA) were utilized to predict
optimized and robust texture designs with reasonable computational effort.
