Annotation

The construction of the drive mechanism of the separator of bulk agricultural products is considered. In the course of theoretical investigations the structural scheme of a vibration separator with a kinematic drive for the excitation of spatial oscillations has been analyzed and specified, and its dynamic model has been refined, which allowed to obtain differential equations of its motion as an electromechanical system. The analysis of the mathematical model of the combined vibration drive has determined the analytical and graphic dependences for its main characteristics, which made it possible to substantiate the operating modes of the investigated separator. The selected actuator is characterized by energy saving on the drive and intensifies the separation process.

Keywords: vibration drive, vibration separator, executive bodies, mechanical vibrations, mathematical models

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.
