Vibrations of machines and structures vanish perfectly at a certain frequency when they have a vibration absorber without damping. But if forced frequencies vary from the anti-resonance frequency, their vibration amplitudes increase signi"cantly. Then the absorber without damping cannot be applied t
A new passive/active dynamic vibration absorber is proposed for structural vibration control. The device consists of two reaction-masses attached to the primary structure through elastic elements. The active force pair is applied between these two reaction masses. This configuration should be contra
