The mathematical model of a vibratory separator with sequential sieve placement, a double independent, unbalanced drive and a spring suspension is constructed. The model is nonlinear, unified and parametric. It is obtained on the basis of the use of the second-order Lagrange equation and the asymptotic methods of nonlinear mechanics. It is obtained on the basis of the use of the Lagrange’s equation second order and the asymptotic methods of nonlinear mechanics. The model is intended to study the dynamics of the separator in the process of its designing and further operation, in particular for selection  its optimal design parameters and determining the conditions of the established and transitional operating modes. It is presented in the form of a set of analytic dependences of the laws of motion of the working body arbitrary points of a vibratory separator with sequential placement of sieves from the geometric, mass-inertial and kinematic parameters of the separator with the possibility of a wide range of their variations. The model can be part of the systems of automated design and calculation of a number of vibratory separators, which differ in number of sieves, location and complexity of the drive, suspension, working body, etc.

Keywords: separator, debalance, nonlinear model, vibration drive, sequential sieves, spring suspension

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.
