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.
