Abstract
A mathematical model for the prediction of relative lifetimes of railway wheels exposed to block braking under stop braking cycles is presented. Analytical and finite element thermoelastic calculations are employed together with a model for low-cycle fatigue. Durability curves are established describing limiting combinations of axle load and train speed for given combinations of signalling distance and required wheel lifetime. Application of the method is demonstrated on an existing freight car wheel which conforms to UIC standards. The numerical results should also be useful for other wheels.
