MAGNETIC FLUID DEVICE FOR DAMPING OSCILLATIONS Russian patent published in 2018 - IPC F16F6/00 F16F9/53 

FIELD: machine building.

SUBSTANCE: invention relates to the field of engineering. In the method, the device comprises a body filled with a magnetic fluid and a rod with a magnetic system movable in the axial direction. In the body an element with throttling channels is located. Said rod with a magnetic system contains a static damper rigidly mounted on it, made of elastic magnetically conductive material. Above body covers the rod, inside which the element with throttling channels of variable cross-section is located, it is permeated by the magnetic field of magnets fixed on the rod. Permanent magnets are installed in the body and have opposite polarity. Further, the space inside the body and the gap between the permanent magnet and throttling channels are filled with a magnetic fluid.

EFFECT: improvement in the damping characteristics is achieved.
