METHOD OF ADJUSTING DYNAMIC STATE OF VIBRATION PROCESS MACHINE AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2020 - IPC F16F15/02 

FIELD: machine building.

SUBSTANCE: invention relates to the field of machine building. Vibrations of the working member of the vibration process machine are excited to record displacement of coordinates of motion. Additional vibration exciter and a pneumatic resilient element are introduced into the system. By varying the position of the pneumatic resilient element relative to the centre of mass of the element system and pressure, the reduced stiffness of the system is controlled therein. Proposed device comprises solid body on resilient supports, vibrating exciter, transducers and additional adjustable resilient element. Additional resilient element is made in the form of a pneumocylinder. Automatic sub-tuning system adjusts pneumatic cylinder parameters.

EFFECT: enabling adjustment of the dynamic state of the object by changing the given stiffness of the system.
