Hydrovolumetric steering systems have today become widely used in heavy agricultural machines, such as combines, loaders, etc. The reliability and quality of operation of these machines largely depends on the quality of these systems and their elements. During the operation of these systems, a number of shortcomings were identified, which require additional research and the application of new design solutions. From the analysis of modern developments of the leading manufacturers of elements of these hydraulic systems, it follows that the main design changes are caused by the need to ensure the operability of these systems in abnormal or emergency situations. To check the performance of these devices in laboratory conditions, it is necessary to provide bench equipment with the ability to simulate abnormal situations and ensure the recording of the received information for the purpose of its further analysis and the formation of a set of measures aimed at eliminating the identified deficiencies and meeting the requirements of current standards.
The authors have developed an original method of experimental research of individual steering control units for hydrostatic steering systems of special vehicles. It is proposed to create a load on the steering control unit in the form of a pressure difference in its output channels without using supporting hydraulic cylinders. To implement the proposed method, an electro-hydraulic scheme of the stand was developed. This makes it possible to analyze the quality of the steering unit's operation in conditions corresponding to different operating modes of the steering system, and to determine the corresponding characteristics of the steering unit under oncoming and passing loads.

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.
