   <abstract xml:lang="ru">
    <p>Цель: Обоснование выбора факторов, определяющих формирование динамической нагрузки на железнодорожный путь со стороны современного подвижного состава при скоростном и высокоскоростном движении. Для достижения этой цели были проведены теоретические предпосылки и экспериментальные исследования. В результате работы разработана методика определения вертикальной расчетной силы, которая действует от колеса на рельс. Методика: Скоростные и высокоскоростные поезда, в силу своей принципиальной конструкции и значительного увеличения скорости движения, требуют пересмотра методов расчета воздействия подвижного состава на железнодорожный путь. Это включает анализ соотношений среднеквадратических отклонений различных динамических сил и оценку влияния различных факторов при разных скоростях движения. Результаты: В рамках работы были проведены экспериментальные измерения для изучения изменений динамической нагрузки. В результате были получены зависимости между средней и расчетной вертикальными силами и скоростью движения для современных пассажирских поездов. С использованием факторного дисперсионного анализа были получены численные характеристики влияния различных факторов на значение вертикальной силы, действующей от колеса на рельс. Также были определены степени влияния различных факторов на формирование этой силы.</p>

    <p>Purpose: Justification of choosing the factors influencing the formation of dynamic load on the railway track by modern rolling stock during high-speed and very high-speed operations. To achieve this goal, theoretical groundwork and experimental research have been conducted. As a result of the work, a methodology has been developed for determining the vertical calculated force exerted by the wheel on the rail. Methods: High-speed and very high-speed trains, due to their fundamental design and significant increase in speed, necessitate a reconsideration of methods for calculating the impact of rolling stock on the railway track. This includes the analysis of relationships between root-mean-square deviations of various dynamic forces and the assessment of the influence of different factors at different speeds of operation. Results: As part of the study, experimental measurements have been conducted to examine changes in dynamic load. As a result, dependencies between the average and calculated vertical forces and the speed of operation for modern passenger trains have been obtained. By using factorial analysis of variance, numerical characteristics of the influence of various factors on the value of the vertical force exerted by the wheel on the rail have been obtained. Additionally, the degrees of influence of different factors on the formation of this force have been determined.</p>
