Важным аспектом повышения точности прогноза напряженно-деформированного состояния дисков железнодорожных колес при действии эксплуатационных нагрузок является учет остаточных технологических напряжений. Настоящая работа посвящена разработке метода учета остаточных технологических напряжений в дисках колес, который обеспечит универсальность подхода и точность расчетов. Анализ напряжений в диске колеса от действия монтажной (натяга между ступицей и осью) и эксплуатационной нагрузки выполнен на основе результатов конечно-элементного моделирования. Проверка адекватности используемой модели проведена путем сравнения расчетной информации с экспериментальными данными АО «Научно-исследовательский институт железнодорожного транспорта». Анализ расчетных и экспериментальных значений радиальных напряжений выполняли для наиболее нагруженных при эксплуатации (опасных) зон диска ‒ зон его сопряжения с ободом и ступицей. Установлено, что заданием величины натяга больше фактической можно получить образование в колесе дополнительных напряжений, которые с достаточной степенью точности отражают влияние остаточных технологических напряжений на напряженно-деформированное состояние диска. На примере расчета колеса с плоскоконическим диском (ГОСТ 10791 – 2011) показано, что увеличение величины натяга на 60 % (c 0,25 до 0,4 мм на диаметр) позволяет адекватно спрогнозировать значения напряжений в наиболее опасных зонах диска. Максимальные относительные отклонения расчетных показателей радиальных напряжений от экспериментальных и по наружной, и по внутренней сторонам колеса, не превышают 14 %. Несмотря на простоту реализации, предлагаемый метод обеспечивает повышение точности прогноза прочностных характеристик колес, а также возможность его использования для различных типоразмеров колес.</p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to development of a method for accounting residual technological stresses in wheel disks, which will provide both the versatility of the approach and the accuracy of calculations. The analysis of stresses in the wheel disk from the action of assembly (interference between the hub and the axle) and operational loads is carried out on basis of the results of finite element modeling. Verification of adequacy of the used model was made by comparing the calculated information with the experimental data of JSC “VNIIZHT”. The analysis of calculated and experimental values of radial stresses was carried out for the most loaded (critical) zones of the disk during operation – the zones of its interface with the rim and the hub. It was found that by setting the interference fit value to be greater than the actual one, it is possible to obtain the formation of additional stresses in the wheel, which, with a sufficient degree of accuracy, reflect the effect of residual technological stresses on its stress-strain state. On the example of calculating a wheel with a flat-conical disk (GOST 10791 – 2011), it is shown that an increase in the interference fit value by 60 % (from 0.25 mm to 0.4 mm per diameter) makes it possible to adequately predict the magnitude of stresses in the most critical disk elements. The maximum relative deviations of the calculated values of radial stresses from the experimental ones, both along the outer and inner sides of the wheel, do not exceed 14 %. Despite the simplicity of implementation, the proposed method provides an increase in the accuracy of predicting the strength characteristics of wheels, as well as the possibility of using it for various standard wheel sizes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>железнодорожное колесо</kwd><kwd>напряженно-деформированное состояние</kwd><kwd>эксплуатационные нагрузки</kwd><kwd>конечно-элементное моделирование</kwd><kwd>напряжения в диске</kwd><kwd>остаточные напряжения</kwd><kwd>натяг между ступицей и осью</kwd><kwd>диск колеса</kwd></kwd-group><kwd-group xml:lang="en"><kwd>railway wheel</kwd><kwd>stress-strain state</kwd><kwd>operational loads</kwd><kwd>finite element modeling</kwd><kwd>stresses in disk</kwd><kwd>residual stresses</kwd><kwd>interference between hub and axle</kwd><kwd>wheel disc</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Liu Yo., Stratman B., Mahadevan S.
