To achieve the goals set, the following tasks were solved: 1. find promising areas of work to modernize the schemes and principles of operation of a hydrostatic transmission of the GTS-90 type. 2. create a mathematical model of hydrostatic transmission type GST-90. 3. Explore ways to improve the technical level and quality of hydrostatic transmission type GTS-90 by mathematical modeling and computer simulation. 4. To develop recommendations for the modernization of the design of hydrostatic transmission type GST-90. The object of research is hydromechanical processes in a hydrostatic transmission of the GST-90 type under different operating modes of agricultural machines. Research methods - theoretical analysis of the processes that determine the characteristics of hydrostatic transmission type GST-90, methods of mathematical modeling using the fundamental laws of hydraulics, hydromechanics and theoretical mechanics. Performing numerical, physical experiments and computer simulations. A review of known designs of rotary piston pumps and their control systems has been made. A mathematical model of the operation of a hydrostatic transmission has been developed, which includes a subsystem of an axial piston pump and a hydraulic motor, consists of equations for the continuity of working fluid flows and equations for force factors acting on the elements of the system. As a result of the research, results were obtained, the analysis of which made it possible to propose an improved design of the hydrostatic transmission pump. Perform mathematical modeling, analyze the model and propose a methodology for engineering calculation of systems of this type.
