Summary

Major types of freight car wheel defects in the Russian Railways, their types and distributions were a subject of field observations, study and simulation. The modelling of defects initiation was performed for wheel loads, dimensions and materials, characteristic for freight car wheels used on the Russian Railways. Modeling is comprised of the calculation of the shape and the size of the contact patch, and the normal pressure distribution between the wheel tread and the rail running surface for new and worn wheel/rail profiles. Analysis of the internal stresses in the wheel was carried out based on the calculated contact normal and tangential stresses using known solutions for concentrated normal and tangential loads applied to the elastic half-space. Particular attention was given to thermomechanical damage of the wheel tread surface. The influence of thermal stresses on the resistance of the material to withstand cyclic loading were simulated.
