TUNED MASS DAMPER WITH TRANSLATIONAL AXIS DAMPING

摘要

A tuned mass damper includes a container having first and second inside wall portions, and a proof mass disposed within the container. Multiple pairs of oppositely directed bellows containing damping fluid are connected between the wall portions and the mass to permit motion of the mass along primary axes. A spring is connected in series with each pair of bellows. The spring has a diameter substantially less than a diameter of the corresponding pair of bellows so that the spring and bellows allow translational movement of the mass about an axis other than the primary axes.
