PROCEDURE FOR DAMPING MECHANICAL OSCILLATIONS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F16F15/27 F16F7/08 

FIELD: machine building.

SUBSTANCE: device for damping mechanical oscillations consists of chamber, of flexible shell installed in chamber and forming pressure tight cavity. A cartridge with slots is installed inside this cavity by means of flanges. By means of pipelines and via an electric valve outside the chamber the pressure tight cavity of the shell is alternately connected to a source of compressed air and to atmosphere via an exhaust branch. A sensor of relative transfers is coupled with input of a control block of the electric valve, outputs of which are connected to winding of movable coils and electric valve. The chamber contains the flexible element and a slotted spring secured on rods and positioned with a little gap between the flexible element and the flexible shell. The procedure for damping mechanical oscillations consists in power and weight transfer between a deformed and an accumulating element by means of discrete commutation of flexible elements.

EFFECT: raised efficiency of oscillation damping in resonance zone.
