Vibration damper system for fluctuations in motion near critical excitation frequency of drive system has section containing deflection masses mounted on rotating disk and section containing flexible component producing restoring force

摘要

The vibration damper system is used for preferential damping of fluctuations in motion in the vicinity of the critical excitation frequency of a drive system. It comprises a first damping section (54) containing deflection masses mounted on a rotating disk whose radial positions alter when they are subjected to fluctuations in motion. A second section (36) contains a flexible component (48) which produces a restoring force when subjected to fluctuations in motion. The two sections reduce fluctuations in two different excitation ranges.
