Abstract [en]

In this work a methodology is presented to assess running gears with respect to wheel and rail rolling contact fatigue (RCF). This assessment is based on wheel/rail contact data for different wheel profile wear states taken from a wheel profile prediction methodology. The approach allows e.g. The assessment of rail RCF in different curve radii in a cumulative way (sum of damage over lifetime of wheel profiles). Furthermore, RCF assessments can be done at different wear states of the wheel profiles to get insight how the contribution to wheel and rail RCF varies depending on the evolution of the wheel profiles. The presented methodology is exemplary applied to two bogie types, the UIC-Y25 standard bogie and the so called FR8RAIL bogie with a mechanical wheelset steering device. The presented methodology is a helpful tool e.g. To optimize vehicles already in an early stage of the development process.
