Mass Dampers in their simplest form are large rubber or metal weights which help prevent structural vibration.They can be designed to suit various applications.
Tuned mass dampers are slightly more complicated they provide a counter balance to the vibration. This allows the vibration or movement of an object to be balanced by a comparatively lightweight component, such as a Trelleborg Reqill damper, countering the vibration and damping of structure borne oscillation.
Trelleborg Resonance Damping today produces dampers with a damping mass in the range from 200 grams to 5,2 Kilograms.
