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 a SFB. 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, recommendations for the economic production of rolling surfaces will be derived.

转移项目将调查表面形态对混合摩擦条件下滚动接触疲劳的影响。计划的调查是基于微观尺度的摩擦模拟模型，材料分析和实验的框架内开发的SFB。滚动疲劳试验、表面表征和材料疲劳模拟的组合应提供关于表面粗糙度对滚动疲劳的寿命影响的信息。借助测试结果，将得出滚动表面经济生产的建议。
