Influence of the surface morphology on the rolling bearing life under mixed friction conditions

The transfer project will investigate the influence of surface morphology on the fatigue of rolling contacts under mixed friction conditions. The planned investigations are based on the micro-scale tribo-simulation model, materials analysis and experiments developed within the framework of SFB 926. This combination of rolling fatigue tests, surface characterization and simulations of material fatigue should provide information about the lifetime influence of surface roughness on rolling fatigue. With the help of the test results, rec-ommendations for the economic production of rolling surfaces will be derived.
