PARAMETER DEVELOPMENT AND ANALYSIS OF THE OSCILLATORY SYSTEM OF A TWO-MASS RESONANT VIBRATING TABLE WITH AN INERTIAL DRIVE

The widespread use of vibrating tables in industry motivates researchers to develop new, efficient designs that can increase production profitability. For this purpose, the authors present a new schematic design of a vibrating table with an inertial drive, proposed to be powered by a hydraulic coupling. The principle of operation is as follows: the driving shaft of the hydraulic coupling is rotated by an electric motor, while its driven shaft is connected to an unbalanced mass.

Substantiation of Parameters and Analysis of Operational Characteristics of Oscillating Systems of Vibratory Finishing Machines

The calculation diagrams of oscillating systems and operation features of vibratory finishing machines are considered. The mathematical models of three-mass and four-mass oscillating systems are presented. The amplitude values of the oscillating masses displacements are derived. The functions of inertial and stiffness parameters optimization are formed. The optimization problems are solved with a help of MathCAD software.
