SYSTEM OSCILLATIONS DAMPING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC F16F9/06 F16F9/53 

FIELD: machine building.

SUBSTANCE: invention relates to machine building. Oscillations are damped by increasing of magnetic fluid viscosity and by excitation of magnetic field pulses in damping magnetic fluid. Magnetic fluid is spatially advances system movable part movement front edge. Creating additional damping of system oscillations in pneumatic resilient element variable volume and hollow plunger constant volume. Device comprises cylinder, filled with magnetic fluid. Solenoid coil covers cylinder. Position and direction meters of piston movement are connected to logical unit data inputs. Outputs of the switchboard are connected with inputs of sections of the solenoid coil. Pneumatic resilient element is arranged in male die. Constant volume hollow piston is rigidly connected with rod. Valve device is installed between pneumatic resilient element and hollow plunger. Power supply source is equipped with piston acceleration sensor.

EFFECT: enabling expanded range of dissipative resistance forces, wider operating range of perceived loads and higher efficiency of damping.
