PROCEDURE FOR DAMPING OSCILLATIONS OF MOVABLE SYSTEM AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F16F9/53 F16F6/00 F16F15/03 

FIELD: machine building.

SUBSTANCE: procedure for damping oscillations consists in generation of additional dissipative force of resistance in zone of damping magnetic fluid by means of excitation of pulses of magnetic field. Magnetic fluid in space advances front of transfer of part of the movable system immersed into magnetic fluid in the direction of transfer. The device for oscillation damping consists of a cylinder filled with magnetic fluid, of a rod and piston movable in axial direction and positioned in the cylinder, of a solenoid coil of several sections enveloping the cylinder and connected to a controlled source of current. The controlled source of current consists of gauges of position and direction of piston transfer, outputs of which are connected to the first and second data inputs of a logic unit. A power input of the logic unit is connected to the current source, while its output is connected with a controlled input of the switchboard. Outputs of the switchboard are connected with inputs of sections of the solenoid coil.

EFFECT: raised efficiency of oscillation damping of movable system.
