Increase in the efficiency of vibration devices due to excitation of low-frequency resonance vibrations

The issues of increasing the efficiency of vibration mechanisms due to the implementation of the mode of multiple Raman parametric resonance are considered. As a drive of the vibration mechanism, it is proposed to use a parametric vibration exciter, in which the driving force is created as a result of the interaction of swinging pendulums located in the field of centrifugal forces of inertia of the rotating rotor and in the field of gravity, with the working body connected to the base by elastic elements.
