Целью исследований является разработка аналитической зависимости между ходом исполнительного механизма электрогидравлического привода и величиной зазора, обеспечивающей реализацию алгоритмов активного регулирования. Объектом исследований является молотильно-сепарирующее устройство тангенциального типа зерноуборочного комбайна ACROS530. Методика основана на кинематическом анализе механизма подвески подбарабанья с использованием геометрического моделирования звеньев и определения координат шарнирных точек через пересечение окружностей. На базе полученной модели вычислены зависимости зазора от хода гидроцилиндра, что позволило сформировать обратную функцию, необходимую для систем управления. Для уменьшения вычислительной нагрузки выполнена аппроксимация методом кубического сплайна, обеспечившая высокую точность в рабочем диапазоне регулирования. Предложенная схема адаптивного электрогидравлического привода включает в себя замкнутые контуры управления положением, скоростью и давлением. Предложенная архитектура отличается пониженным энергопотреблением при удержании нагрузки и возможностью адаптации к изменяющимся условиям работы. Результаты исследований могут быть использованы при проектировании и модернизации систем регулирования молотильно-сепарирующих устройств современных зерноуборочных комбайнов</p></abstract><trans-abstract xml:lang="en"><p>Adjusting the concave clearance in a threshing-and-separating unit of a combine harvester directly impacts threshing quality and grain loss. This study aims to develop an analytical relationship between the actuator stroke of the electro-hydraulic drive and the clearance size, enabling the implementation of active control algorithms. The research focuses on the tangential-type TSU of the ACROS530 combine harvester. The methodology is based on a kinematic analysis of the concave suspension mechanism, utilizing geometric modeling of the links and determining joint coordinates via the intersection of circles. Based on the resulting model, the authors established the relationship between the clearance and the hydraulic cylinder stroke to formulate the inverse function required for control systems. To minimize computational load, a cubic spline approximation was performed, ensuring high precision within the operational regulation range. The proposed adaptive electro-hydraulic drive scheme incorporates closed-loop control for position, speed, and pressure. The proposed architecture is characterized by reduced energy consumption during load holding and the ability to adapt to varying operating conditions. The study results can be applied to the design and modernization of regulation systems for the threshing and separating units of modern combine harvesters</p></trans-abstract><kwd-group xml:lang="ru"><kwd>регулирование зазора молотильно-сепарирующего устройства</kwd><kwd>подбарабанье</kwd><kwd>комбайн</kwd><kwd>молотильно-сепарирующее устройство</kwd><kwd>схема адаптивного электрогидравлического привода</kwd><kwd>гидроцилиндр</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adjusting the concave clearance of the threshing-and-separating unit</kwd><kwd>concave</kwd><kwd>combine harvester</kwd><kwd>threshing-and-separating unit (TSU)</kwd><kwd>adaptive electro-hydraulic drive circuit</kwd><kwd>hydraulic cylinder</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">Папаскири Т.В., Митрофанов С.В., Богданчиков И.Ю. и др.
