DYNAMIC OSCILLATION SUPPRESSOR Russian patent published in 2001 - IPC

FIELD: apparatuses for suppressing oscillations by action of dynamic loads. SUBSTANCE: dynamic oscillation suppressor includes weight of suppressor in the form at least of two pendulums with their rocking axes, driving device with shaft for rotating said weight and intermediate members joining weight with shaft. Suppressor is provided with control system including pickups for measuring oscillation parameters of protected object; electronic unit for analysis of pickup signals; servodrive controlled by means of electronic unit, lever, coupling and tie rods transmitting control action of servodrive to intermediate members. The last are in the form of levers whose one end is kinematically joined with shaft and whose other end is joined with rocking axes of pendulums. Such design allows to increase range of suppressed frequencies and to provide automatic servotuning of suppressor to frequency of disturbance at constant mean angular velocity of rotating shaft. EFFECT: improved design. 2 cl, 4 dwg
