Abstract: Predicting fatigue and wear on wheels and rails is a key to nd ways to improve the service life of a railway track and the rolling stock. Rails experience contact with a range of wheel pro les that will pummel their surface at different positions with different intensities. This work compares two methods for evaluating pummelling analyses for the wheel-rail interaction: simpli ed quasi-static model and multibody dynamics simulations. The rst one is solved using the GIRAFFE program and simulates the interaction… Show more
