Active torsional vibration damper

The Journal of the Acoustical Society of America, 1997
A resonance torsional vibration damping system includes a member having at least one node location along its length. An energy exchanging device, such as a fly wheel and eddy current brake, is operably connected to the member at a damping location that is a distance away from the at least one node location.

Torsional Vibrations of Elastic Prolate Spheroids

The Journal of the Acoustical Society of America, 1968
Frequency equations and mode shapes are presented in analytic form for the torsional vibrations of solid prolate spheroids and thick prolate spheroidal shells. The solutions are shown to include the previously obtained solid sphere and thin prolate spheroidal shell results as limiting cases. Numerical results are presented for solid prolate spheroids.

VIBRATION CONTROL STRUCTURE UTILIZING TORSIONAL VIBRATION

In 2010, the authors developed a response control structure that utilizes torsional vibration of buildings and presented its concept and principles of response control. This structural system consists of an eccentrically arranged core structure and a pin-jointed damper frames surrounding the building’s perimeter.
