      <abstract xml:lang="ru">
        <p>В силу того, что нагрузки, возникающие в рабочем оборудовании карьерных экскаваторов, определяются большим числом случайных факторов, сложно представляемых аналитическими формулами, для оценки и прогнозирования нагрузок необходимо внедрять модели с использованием нестандартных подходов. В настоящем исследовании использована методология теории нечеткой логики и нечетких множеств, позволяющая преодолеть трудности, связанные с неполнотой и расплывчатостью данных при оценке и прогнозировании усилий, возникающих в рабочем оборудовании карьерных экскаваторов, а также с качественной природой этих данных. В результате компьютерного моделирования в среде fuzzyTECH для определения уровня нагруженности основных элементов рабочего оборудования карьерных экскаваторов получены сопоставимые с экспериментальными исследованиями данные. На основе репрезентативной выборки произведен статистический анализ данных, вследствие чего получено уравнение линейной множественной регрессии напряжений в рукояти карьерных экскаваторов, которое позволяет составить точный прогноз нагруженности рабочего оборудования экскаватора.</p>

        <p>Due to the fact that the loads occurring in the working equipment of mining excavators are determined by a large number of random factors that are difficult to represent by analytical formulas, for estimating and predicting loads the models must be introduced using non-standard approaches. In this study, we used the methodology of the theory of fuzzy logic and fuzzy pluralities, which allows to overcome the difficulties associated with the incompleteness and vagueness of the data in assessing and predicting the forces encountered in the working equipment of mining excavators, as well as with the qualitative nature of these data. As a result of computer simulation in the fuzzyTECH environment, data comparable with experimental studies were obtained to determine the level of loading of the main elements of the working equipment of mining excavators. Based on a representative sample, a statistical analysis of the data was performed, as a result of which the equation of linear multiple stress regression in the handle of mining excavators was obtained, which allows to make an accurate forecast of the loading of the working equipment of the excavator.</p>
