Abstract [en]

A model which can predict the surface crack length and crack depth in rails was developed in a previous study by the authors1. In the present study, this crack prediction model in combination with a wear prediction model is verified against wheel measurements. For a period of 15 months, the wheels of three units of a Stockholm commuter train were measured with respect to wear and crack development. Vehicle-track dynamics simulations were used to calculate the forces and contact positions for the wear and crack prediction models. It can be concluded that the wear prediction model gives reasonable results, especially considering the large scatter in the wheel profile measurements. Although the crack prediction model had to be adjusted for the current wheel application, the results appear promising.
