FIELD: mechanical engineering. SUBSTANCE: invention relates to means of vibration protection of different objects. According to invention device contains thin-walled closed cylindrical envelope with cross corrugations reinforced by outer metal shaped rings placed in valleys of corrugations between their crests and partially filled with damping medium. Metal shaped rings are made in form of axially magnetized permanent magnets of different thickness with unlike poles pointed to each other. Ferromagnetic liquid is used for filling the envelope. EFFECT: improved efficiency of vibration protection and reliability of device at considerable vibration overloads. 1 dwg |
