VIBRATION EXCITATION METHOD Russian patent published in 2020 - IPC B06B1/16 

FIELD: machine building.

SUBSTANCE: invention relates to vibration equipment and can be used in vibration machines used in solid media dispersion, including during processing of wastes, as well as in construction, transport, medicine, metalworking, agriculture, machine building, food, mining and other industries, where vibration with different vibration laws is used. Method of excitation of oscillations consists in the fact that two rotary bodies are conjugated by end surfaces with calibrated pressing force and, simultaneously rotating them in different directions with different angular velocities, rolling each along its own closed trajectory, having rotary symmetry around axis of symmetry of trajectory, at the same time, but not synchronously, they are exposed to two unbalanced radial forces and continuously change their direction with rotation frequency of at least one of the rotated bodies, thus, in the system oscillations with modulated properties are mechanically generated, which form volumetric vibrational fields of complex shape.

EFFECT: broader technological capabilities of the method by generating and controlling a complex shape of a volume vibration field generated by oscillations with modulated properties.
