TLDR
The revolution vibration absorber, mainly used for the crankshaft of a vehicle, consists of several weights, radial arranged around the hub and joined to the hub with bolts, moving in curved slots as mentioned in this paper.Abstract:
The revolution vibration absorber, mainly used for the crankshaft of a vehicle, consists of several weights (2), radial arranged around the hub (1) and joined to the hub with bolts (5), moving in curved slots (4,9,12). Vibrations caused by the rotating crankshaft are absorbed by an oscillating and longitudinal rocking motion of the weights. At least one of the slots (9,12) is joined to a lubrication system (7,17) in order to reduce premature wear and tear of the parts.read more

Torsional vibration damper
TL;DR: A torsional-vibration damper comprises three concentric ring elements being a hub ring, a flywheel ring and an elastic ring as discussed by the authors, and the operating frequency is dependent on anguular speed such that as the angular speed increases, the effective operating frequency of the tornsional vibration damper is shifted higher.
