Abstract
This paper proves in experimental terms the high efficiency of a new type of wideband frequency passive dynamic vibration absorber (PDVA) useful in dynamic behaviour correction of mechanical structures. The PDVA uses a mass and a mechanical elastic suspension based on a visco-elastic polymer (e.g. SORBOTHANE). For damping efficiency evaluation was used an experimental set-up based on a low natural damped cantilever beam with a mass and a PDVA placed at the free end. The damping effect (up to 27 dB attenuation and 60 Hz wideband frequency) is generated by the coresonance between the mechanical structure and PDVA. [ABSTRACT FROM AUTHOR]
