text: Radial shaft seals are used in a variety of applications, where rotating shafts
in steady housings have to be sealed. Typical examples are crankshafts, camshafts,
differential gear or hydraulic pumps. In the operating state the elastomeric seal
ring and the shaft are separated by a lubrication film of just a few micrometers.
Due to shear strain and fluid friction the contact area is subject to a higher
temperature than the rest of the seal ring. The stiffness of the elastomeric material
is intensely influenced by this temperature and thus contact pressure, friction
and wear also strongly depend on the contact temperature. In order to simulate
the contact behavior of elastomer seal rings it is essential to use a comprehensive
approach which takes into consideration the interaction of temperature, friction
and wear. Based on this idea a macroscopic simulation model has been developed
at the MEGT. It combines a finite element approach for the simulation of contact
pressure at different wear states, a semi-analytical approach for the calculation
of contact temperature and an empirical approach for the calculation of friction.
In this paper the model setup is presented, as well as simulation and experimental
results.

text: 'A profound description of friction in wheel--rail contact plays an essential
role for optimization of traction control strategies, as input quantity for railway
simulations in general and for the estimation of wear and rolling contact fatigue.
A multitude of wheel--rail contact models exists, however, traction--creepage
curves obtained from measurements show quantitative and qualitative deviations.
There are several phenomena which influence the traction--creepage characteristics:
Mechanisms resulting from surface roughness, frictional heating or the presence
of interfacial fluids can have a dominating influence on friction. In this paper,
a new wheel--rail contact model, accounting for these influential parameters,
will be presented. The presented model accounts for the interaction of an interfacial
fluid model for combined boundary and mixed lubrication of rough surfaces with
a wheel--rail contact model that additionally accounts for frictional heating.
A quantitative comparison with measurements found in the literature is not conducted,
since the exact conditions of the measurements are mostly unknown and parameters
can easily be adjusted to fit the measurements. Emphasis is placed on the qualitative
behavior of the model with respect to the measurements and good agreement is found.
The dependence of the maximum traction coefficient on rolling velocity, surface
roughness and normal load is studied under dry and water lubricated conditions.'
