Based on the analysis of modern designs of domestic and foreign agricultural machines, it was established that one of the most responsible systems that affect the operation and reliability of this equipment is the volumetric hydraulic drive. The hydraulic drive is also the most complex system of modern self-propelled machines, the use of hydrostatic transmission is a particular difficulty for operators HST-112, which is increasingly used on self-propelled machines and tractors. The article describes the structure and principle of operation of the volumetric hydrostatic transmission HST-112, and also presents its mathematical model in the braking mode of a self-propelled agricultural machine. The developed mathematical model makes it possible to understand and predict the operation of volumetric hydrostatic transmission under different conditions of load and pressure of the working fluid. The mathematical model takes into account the variable technological load acting on the working bodies of the volumetric hydrostatic transmission under different operating conditions of the self-propelled agricultural machine. The mathematical model of the HST-112 volumetric hydrostatic transmission as a part of a self-propelled agricultural machine was studied in the Mathcad software, which made it possible to understand what factors affect the efficiency of the transmission and how they can be optimized. As a result of the research of the mathematical model, the characteristic features of the work of the volumetric hydrostatic transmission HST-112 and its individual components in the presence of a significant inertial load were revealed. The mathematical model was developed on the basis of fundamental laws of hydraulics, hydromechanics, theoretical mechanics and real characteristics of drives of mobile agricultural machines. Based on the theoretical analysis of the processes that determine the characteristics of the hydrostatic transmission, it was established that with significant inertial loads on the executive hydraulic motor, processes occur that can lead to a decrease in its working life, wear resistance, and deterioration in reliability. The developed mathematical model calls for further experimental research in order to establish rational parameters of volumetric hydrostatic transmission.

Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
