In this scientific article, the levels of residual technological stress in the disks of solid-rolled wheels of freight and passenger cars were determined using the strain gauge method. For this, an experiment was carried out with the objects of research. For objects of study, different types of wheels were selected. The experiments were carried out according to the European EN 13262:2004+A2:2011 and between the state GOST R 54093-2010 standards. After the experiment, all data was processed and plots were prepared for all types. From the diagram, the level of residual stresses in the transition of the disk of solid-rolled wheels of wagons was determined.

В данной статье анализируются неисправности колесо, связанные с диском всего подвижного состава. За последние 10 лет было изучено количество случаев сбоев подачи с помощью колесного диска и их размеры. Кроме того, учитывался сезонный характер сбоев, в какое время года наблюдается больше всего. Также были проанализированы средняя длина трещин в колесах с течением времени, а также наиболее заметные
размеры. Длина образования трещин была проверена для среднеквадратичного отклонения, и ее значение оказалось равным 124 мм. На основе среднеквадратичного отклонения рассчитывают коэффициент образования трещин в диапазоне от 68 мм до 316 мм, т.е. коэффициент вариации. Вариационный коэффициент составил 0,66.
