In this paper, a new concept for the calculation of mixed lubrication is presented. Using the finiteelemente-
method (FEM), the load and friction forces are calculated separately for lubricant and solid.
Thereby, the fluid-structure-interaction (FSI) between lubricant pressure and solid deformation is taken
into account. The finite-elemente model is based on real 3D surface roughness measurements using a
stylus profilometer. The surface profiles are discretized into rectangular poles. In order to solve the FSI
problem, the flow calculation is interlinked with the structural calculation.
For the oil-lubricated tribological system linear thrust bearing (material: G-CuZn15Si4) and steel
counterpart (material: Ck45), the calculations are verified for static load, slow oscillating movements
and different bearing temperatures.
