Abstract
An auxiliary torsional damper of the surface-effect type capable of damping torsional spikes which may occur during operational transition through the system's resonance frequency. Preferably, the auxiliary damper will be designed with a decoupling feature such that the damper will only provide auxiliary torsional damping for torsional oscillations which surpass a threshold amplitude. Since the surface-effect damper is deflection dependent, the larger the magnitude of the torsional spike, the larger the damping that will be applied thereto.
