Prediction of wheel profile wear and rolling contact fatigue for the Stockholm commuter train

• Although several models exist to predict rolling contact fatigue (RCF) or wear, only a few models exist which can predict both. RCF and wear interact with each other, therefore a model has to be developed that can calculate both RCF and wear in order to get a lifetime prediction tool for railway wheels and rails. In this study, vehicle dynamics simulations were performed with the models of two different vehicle types running on the Stockholm commuter network. The performance of these vehicles has been studied with respect to wear and RCF by importing the output from the vehicle dynamics simulations into different wear and RCF models. The performance of these prediction models has also been studied. The influences of several parameters on the behavior of both the vehicles and the prediction models were studied. The results show that not only the vehicles behave differently, but also the wear and RCF prediction models.
