Annotation

High-frequency oscillations are widely used to intensify various technological processes. An analysis of known methods was carried out to study the motion of bulk material on a sloping surface, which performs lineal or lateral oscillations. Thus, we prepared a mathematical model of bulk material motion in a rectangular gutter transmitting high-intensivity fluctuations in plane surface with largest inclination. By experiment we found out that such under such oscillations the material saves the gutter shape and therefore its movement can be considered as the motion of a solid body on a sloping surface. With the averaging-out method we obtained an approximate equation ssolution of this motion, which moderately corresponds to the results of experimental studies. Received relations of the average velocity of bulk material on gutter surface from the its inclination angle to the horizon and the material slip friction coefficient on this surface can be used in engineering calculations to solve specific practical problems.

Keywords: bulk material, gutter, vibration, averaging-out method, average velocity, amplitude, frequency of oscillations

History of journal:

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  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS 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.
