			<abstract xml:lang="ru"><p>Эффективность функционирования гидравлических экскаваторов в условиях экстремальных температурных режимов представляет собой критически важную проблему современного строительного машиностроения. Температурные воздействия оказывают существенное влияние на реологические характеристики рабочих жидкостей гидравлических систем, что непосредственно сказывается на производительности стрелового оборудования. Исследование направлено на разработку комплексной методики оптимизации гидравлических параметров с учетом температурных факторов, влияющих на вязкостно-температурные свойства рабочих сред. В ходе экспериментальных исследований были проанализированы гидравлические системы экскаваторов различных типоразмеров при температурных режимах от -40^{\circ}C до +60^{\circ}C. Комплексный анализ включал измерение динамической и кинематической вязкости гидравлических жидкостей, определение коэффициентов потери мощности и оценку эффективности работы стрелового механизма. Результаты показали, что отклонение рабочей температуры гидравлической жидкости от оптимального диапазона на 10% приводит к увеличению энергетических потерь на 3-12%. Оптимизация параметров позволила повысить энергетическую эффективность гидравлических систем на 18-26% и снизить износ компонентов на 15-20%. Разработанные алгоритмы управления обеспечивают адаптивную коррекцию рабочих параметров в реальном времени в зависимости от температурных условий эксплуатации. Практическая значимость исследования заключается в возможности существенного повышения эксплуатационной надежности и энергоэффективности строительных машин в различных климатических условиях, что особенно актуально для регионов с резко континентальным климатом.</p></abstract><trans-abstract xml:lang="en"><p>The efficiency of hydraulic excavators in extreme temperature conditions is a critically important problem in modern construction engineering. Temperature influences have a significant impact on the rheological characteristics of hydraulic system fluids, which directly affects the performance of boom equipment. The research is aimed at developing a comprehensive methodology for optimizing hydraulic parameters, taking into account temperature factors affecting the viscosity-temperature properties of working media. In the course of experimental studies, hydraulic systems of excavators of various sizes were analyzed at temperatures from - 40^{\circ}C to +60^{\circ}C The comprehensive analysis included measuring the dynamic and kinematic viscosity of hydraulic fluids, determining power loss coefficients, and evaluating the efficiency of the boom mechanism. The results showed that a 10% deviation of the operating temperature of the hydraulic fluid from the optimal range leads to an increase in energy losses by 3-12%. Optimization of the parameters made it possible to increase the energy efficiency of hydraulic systems by 18-26% and reduce component wear by 15-20%. The developed control algorithms provide adaptive correction of operating parameters in real time depending on the operating temperature conditions. The practical significance of the study lies in the possibility of significantly improving the operational reliability and energy efficiency of construction machinery in various climatic conditions, which is especially important for regions with a sharply continental climate.</p></trans-abstract><kwd-group xml:lang="en"><title>Keywords</title><kwd>hydraulic parameters</kwd><kwd>excavator</kwd><kwd>boom equipment</kwd><kwd>extreme temperatures</kwd><kwd>viscosity</kwd><kwd>energy efficiency</kwd><kwd>optimization</kwd></kwd-group><kwd-group xml:lang="ru"><title>Ключевые слова</title><kwd>гидравлические параметры</kwd><kwd>экскаватор</kwd><kwd>стреловое оборудование</kwd><kwd>экстремальные температуры</kwd><kwd>вязкость</kwd><kwd>энергоэффективность</kwd><kwd>оптимизация</kwd></kwd-group><funding-group>
