FIELD: machine building.
SUBSTANCE: device includes antivibration panel installed on springs, and symmetrically located load-carrying group of eight accelerometres and eight magnetic electric propellers. Device includes electronic control circuits including summators converting signals of accelerometres U1…U2 to signals of three longitudinal U(LX), U(LY), U(LZ) and three torsional U(TX), U(TY), U(TZ) modes of oscillations for six automatic controls. Electric circuits include double integrators compensating false signals of inclination of accelerometres performing angular vibrations in the Earth's gravitational field. Oscillations of vibration source installed on vibration insulating panel on springs are localised as a result of active suppression of oscillations of antivibration panel performing the functions of active acoustic reflection shield in frequency range of 0.2 Hz - 500 Hz.
EFFECT: improving active insulation and localisation of vibration sources.
