The article presents the results of experiments to evaluate vibration parameters when using spatial oscillation excitation drive. Among the main directions of the intensification of the vibration technological action during separation of bulk agricultural products, not only the adjustment of amplitude-frequency characteristics can be noted, but also the improvement of the geometric and structural parameters of the drive mechanisms. Currently, in the processes of separation or classification of bulk masses by the method of siting separation, fixed sieves are displaced by sieves receiving an additional power pulse in order to intensify this processing process. The developed scheme of the drained vibration process involves the oblique location of the working body, which allows to implement the creation of spatial oscillations of the sieve surface. The developed experimental model of the spatial oscillation screen and the studies carried out to obtain graphic dependence of the energy consumption on the process of treating crushed grain material from changes in mass, geometric and structural parameters of the oscillating system. When choosing a rational mode of vibration cutting of bulk products as the evaluation criteria used the eccentricity of the drive shaft, the angle of the tilt surface, the value of the energy consumption and the pattern of its change in the conditions of variation of the power pulse when the eccentricity of the drive shaft, the trajectory of the movement of the sieve elements and the, bulk mass by changing the angle the inclination of the working container, the measurability of the oscillatory movement from the flat to the spatial parameters of the developed vibro-industry, corresponding to the configuration of the structural parameters. Experimental studies have shown the effectiveness of the use of spatial oscillations of the sieve surface during separation of bulk masses, made it possible to substantiate the structural parameters of the vibratory screen.

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"
