EXPERIMENTAL RESEARCH ON THE DISTRIBUTION DYNAMIC PRESSURE OF THE CIRCULATION MOVEMENT OF THE WORKING ENVIRONMENT IN TOROIDAL MOBILE CONTAINERS
Yaroshenko Leonid Victorovich - candidate of technical sciences, associate professor of the department of electric power engineering, electrical engineering and electromechanics of Vinnitsa national agrarian university, Service address: Vinnitsa, st.Sonyachna 3, VNAU 21008, e-mail: volvinlv@gmail.com
In the operation of vibrating process machines for machining parts with a bulk working medium in a vibrating container, individual particles of this medium carry out a chaotic movement, and the whole mass of the bulk medium performs a circulatory motion that has a dynamic effect on the surface of the workpiece in the form of the total impact of many micro-impact parts. However, the velocity of movement and the dynamic impact of the particles of the working medium are not the same in different zones of the container. The distribution of the dynamic pressure of the circulating motion of the working medium in the vibrating toroidal containers is of considerable practical interest in the development of the structures of such vibrating machines and the technological processes of their operation.
The distribution of the dynamic pressure of the working environment during the intersection of the toroidal container of vibrating technological machines with electromechanical drive and vertical unbalance shaft is experimentally investigated, which allows us to determine the most advantageous locations of the work pieces during their vibration treatment based on the conditions of efficiency and processing quality as well as maximum utilization of the kinetic energy of the circulating traffic of working environment when using it for additional forced movement on work pieces. Circulating movement creates the greatest dynamic pressure in the lower zones of the container, and as the distance from the surface of the container increases - dynamic pressure gradually decreases. The magnitude and nature of the distribution of the dynamic pressure of the working environment are also influenced by the direction of its circulation. When pressed by circulating movement of the environment to the outer cylinder of the working surface, ie to the points of the surface of the container having a large amplitude of vertical oscillations, the zone with high dynamic pressure is greater than in the case pressing it the inner cylinder of the working surface of the topper, that is, to the surface points of the container that have a smaller amplitude of vertical oscillations, thus reducing the absolute magnitude of the pressure.

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. 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.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
