Abstract
In one aspect, a tunable vibration damper may include a housing and a damper stack disposed within the housing. The damper stack may be formed from a viscoelastic material and may have a vertical stiffness and a horizontal stiffness. The damper stack may also include a plurality of column sections and a plurality of disk sections, with each pair of adjacent column sections being separated by one of the disk sections. The disk sections may extend radially outwardly relative to the column sections. In addition, at least one of the vertical stiffness or the horizontal stiffness may be tunable by adjusting a stiffness-related parameter of the damper stack.
