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

FIELD: vibration equipment.

SUBSTANCE: invention relates to vibration equipment and can be used in vibration machines used in construction, transport, medicine, metalworking, agriculture, machine building, food, mining and other industries, where vibration is used. Technical effect is achieved due to that two rotation bodies are simultaneously exposed to unbalanced radial force and constantly changing its direction with rotation frequency of said bodies, wherein total amplitude of oscillations is controlled by ratio , where F₃ is unbalanced radial force; Δω=ω'+ω_3; ω' = ω₁ = ω₂ – vibrations frequencies of rotated bodies in synchronous operation mode; ω₃ is unbalanced radial force rotation frequency; M is total mass of bodies; r = r₁ = r₂ are radii of rotated bodies; t is time.

EFFECT: higher efficiency and versatility of vibration excitation method, broader functional capabilities of vibration drives, as well as possibility to unload the drive from actions of dynamic pressures.
