Determination of the resource of wheel pairs of locomotives during operation on the railways of Uzbekistan

The object of the study is the interaction of the electric locomotive wheel pair and the rail. The subject of the research is the wheel resource. The paper proposes a model for calculating the resource mileage of the electric locomotive wheel pair. The basis of the model is the determination of contact stresses in the wheel pair. The proposed calculation model, when changing the input data, can be used to determine the resource of various wheel pairs and traffic safety, and resource savings.
