Abstract
A vibration damping assembly for a wheel or the like that undergoes rotation is achieved by providing an annular groove in a surface of the wheel which is coaxial with the axis of the wheel. A viscoelastic damping material subject to shear deformation during rotation of the wheel is positioned within the groove against the surface of the groove, and an annular metal ring is positioned in the groove against the viscoelastic damping material with the damping material sandwiched between the ring and wheel.
