Abstract
A vibration damping apparatus including an annular housing, a cavity between an internal diameter and an external diameter of the housing, and a substantially solid vibration damping material disposed in the cavity. The vibration damping material has a density that is greater than a density of the housing material. In one embodiment of the invention, the internal diameter and the external diameter of the housing are selected so as to maximize an amount of vibration damping material with respect to a selected tensile strength for the housing. In another embodiment of the invention, the internal diameter and the external diameter of the housing are selected so as to maximize an amount of vibration damping material with respect to a selected bending strength for the housing.
