harmonic oscillations

The article addresses excessive energy consumption in resonance vibration machines with inertial drives, widely used in mechanical engineering, construction, chemical, metallurgical, and mining industries. Conventional design approaches limit energy efficiency, motivating the modernization of one- and two-mass resonance systems into three-mass inter-resonance configurations. Using a method for determining inertia–stiffness parameters, the study ensures synchronous inter-resonance oscillatory modes, enhancing dynamic amplification and reducing drive power.

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.
