Evaluation of the wear of the tire wheel pair at rolling friction

Traffic safety and the main technical and economic indicators of the rolling stock largely depend on the interaction of the wheel and rail, so it is extremely important to determine the intensity of wear on the wheel surface at various stages of the wheels et operation. The article offers modeling of wheel rolling surface wear under rolling friction by the method of maximum contact stresses. The regularity of changes in deformations, stresses and wear intensity of the wheel rolling surface in the area of contact with the rail is established. The method given in the article is tested based on statistical data of the electric locomotive repair shop in the locomotive depot "Uzbekistan “of the joint-stock company “Uzbekistan Temir Yullari".
