Аннотація: The vast majority of modern research on the study of hydromechanical systems is based on the use of the theory of automatic control and management. One of the main components of technical machines and cells are their drives. Hydraulic drives are often used as power. In general, its functional and operational characteristics have a decisive influence on the properties of hydrodynamic systems and general technical machines. In this regard, close attention is paid to the study of hydraulic power drives. However, the power hydraulic drive of technical machines and units in one form or another necessarily includes both electric and mechanical drives, which turns it into a system of various drive systems. The vast majority of modern research is devoted to the study of hydraulic drives, which are based on spool-type hydraulics, which limits the possibility of using new structural materials in the drive systems of technical machines. Many technical machines and installations, especially in agro-industrial complexes, work in harsh conditions, with high temperatures and dust, low quality of working fluid and other unfavorable characteristics that significantly reduce the reliability of drive systems equipped with hydraulic spool types and quality equipment. At current levels of working pressure in the hydraulic system, the forces and speeds of the working bodies of technical machines and units of the agro-industrial complex, the compressibility of the working fluid and the flexibility of the hydraulic elements of the drive system are determined, become noticeable, which requires further improvement of theory and methodology. The theoretical basis of the method of calculating the equipment drive system has been improved on the basis of the complex characteristics of the hydraulic system introduced by the author - the resulting volumetric stiffness is used to simplify the drive modeling process by increasing the accuracy of calculation and analysis of its results.
