ABSTRACT:
A tuned mass damper incorporating a container with an inside surface, two end portions and a mass mounted for oscillation between the end portions by a pair of bias springs, the two end portions being filled with a compressible gas to reduce the effects of temperature variations on the damping characteristics, to increase the damping with increased amplitude of oscillation of the mass and to minimize size and weight of the damper, the mass being supported for oscillation by using a plurality of grooves at each end of the mass with a single ball in each groove to provide frictionless and self centering motion of the mass.
