METHOD OF OSCILLATION EXCITATION Russian patent published in 2014 - IPC B06B1/00 

FIELD: machine building.

SUBSTANCE: method of oscillations excitation implies that a rotated body and a counterbody are conjugated with calibrated pressing force and rolled along the closed trajectory having rotation symmetry around the trajectory symmetry axis, and they are simultaneously exposed to the action of unbalanced radial force with its direction being constantly varying by the body rotation frequency, the total oscillation amplitude is controlled as per the ratio where Δω=ω₁+ω₂; F₂ - rotating unbalanced radial force; ω₁ - oscillation frequency of the rotated body; ω₂ - rotation frequency; r₁ - radius of the rotated body; M - total weight of the bodies; t - time.

EFFECT: improved efficiency and universality of oscillation excitation method consisting in the provision for the possibility to control the form of oscillation motion trajectory and possibility to obtain high-frequency and low-frequency component of the oscillations simultaneously, synchronize them and adjust the parameters of these oscillations.
