Rail RCF damage quantification and comparison for different damage models

Abstract: There are several fatigue-based approaches that estimate the evolution of rolling contact fatigue (RCF) on rails over time and built to be used in tandem with multi-body simulations of vehicle dynamics. However, most of the models are not directly comparable with each other since they are based on different physical models even though they shall predict the same RCF damage at the end. This article studies different approaches to quantifying RCF and puts forward a measure for the degree of agreement between the… Show more

“…Therefore, can we use the FWHM values as a critical parameter to predict the degree of surface contact fatigue damage for practical application with an X-ray diffraction analyzer? In addition, if the bearing inner ring is improperly ground during the production process, it will cause substantial grinding residual stress, and cracks will be caused when this residual stress is too large [24][25][26][27]. At the same time, during contact fatigue, the evolution of residual stress changes the state of surface shear stress [28][29][30].…”
