Properties and Applications of the Electrohydraulic Servosystem of the Hydraulic Excavator
The service of a hydraulic excavator is complicated by poor environment. The safety and stability of the control system are influenced by external factors. The object of the study is the electrohydraulic servosystem of the hydraulic excavator. The mathematical and simulation models using AMESIM for...

Эксплуатация гидравлического экскаватора осложняется наличием неблагоприятной рабочей среды. Показано воздействие внешних факторов на надежность и стабильность системы контроля. Исследована электрогидравлическая сервосистема гидравлического экскаватора. Построены математическая и имитационная модели для сервосистемы с использованием программы AMESIM. Выполнен анализ характеристик давления и текучести. Описаны конструкция и оптимизация электрогидравлической сервосистемы, а также ее применение в экскаваторной технике. Процесс функционирования электрогидравлической сервосистемы представлен кривой, которая круто идет вверх (период подъема), а затем выходит на плато (период стабилизации), эти периоды сокращаются на 38,0 и 40,5% соответственно, период слежения за задержкой на 52,6% при эффективной помехоустойчивости. 2018 Article Properties and Applications of the Electrohydraulic Servosystem of the Hydraulic Excavator / W.H.
