Abstract
A tuned mass damper is provided for use with a structure that vibrates at a first axial surge mode and a second axial surge mode, when exposed to a predetermined frequency range. The tuned mass damper includes a housing, an endcap, two masses, and two springs. The first and second masses are disposed in a housing cavity. The first tuned mass damper spring is disposed in the cavity coupling the first mass and the endcap. The second tuned mass damper spring is disposed in the cavity coupling the first and second masses. The tuned mass damper has first and second resonant frequencies in the predetermined frequency range to damp the first and second axial surge modes, respectively. The second mass resonates at an amplitude that is greater than an amplitude at which the first mass resonates, when the two masses are subjected to the second axial surge mode.
