CONSIDERATIONS ON RECENT TRENDS IN RAILWAY WHEEL DESIGN

This article discusses the use of numerical modelling in the design and damage evaluation of railway vehicle wheels. A global scale model is developed based on railway dynamics to predict the forces that arise at the point of wheel-rail contact. Substantial progress has been made by applying multibody system analysis. The method uses ultrasonic responses to assess the level of contact. Finite element and boundary element analyses are used to model the results. Wheel damage types studied include thermal cracks and brittle fracture, shelling, surface fatigue and wear. Numerical modelling helps to define appropriate configurations of the wheels to avoid plastic strain. Rolling contact fatigue can be predicted by non-linear finite element analysis. Research results must be implemented in easy-to-use codes of practice for design and maintenance routines.
