FIELD: machine building.
SUBSTANCE: method involves two-stage vibration damping using the main and additional elements. Two forces directed in opposite direction and providing mutual damping of horizontal vibrations are applied to additional intermediate platform. Additional forces for damping of vertical forces are applied to vibrators by means of joint variation of radii of two imbalances. Device for implementation of the proposed method includes anti-vibration system containing two controlled inertial rotational vibrators, which are installed on intermediate platform. Two imbalances with varying dynamic action due to adjustment of imbalance radius are installed on vibrators.
EFFECT: control of stiffness of anti-vibration system is achieved.
