Abstract
A spare tire tuned mass damper assembly is provided for reducing vehicle vibration or beaming shake that may otherwise be perceptible at the driver interface. The assembly is attachable between a pair of underbody support beams and includes a tire carrier for a spare tire and wheel and a plurality of spring and damper assemblies positioned between the carrier and support beams. The assemblies have at least one leaf spring and bushing, and are selected to provide a predetermined level of vibration modes and modal damping for the assembly. A method is also provided for reducing road vibration in a vehicle having an underbody support structure, including supporting a spare tire carrier using a plurality of spring and damper assemblies configured to absorb and damp an oscillating mode of the support structure to a predetermined level to produce a desired post-damped road response, thereby increasing vehicle ride comfort.
