TUNED DYNAMIC VIBRATION ABSORBER

摘要

A vibration absorber is provided for reducing noise and vibration emanating from an electric motor, or another vibrating object, and the surrounding structure to which it is mounted. The vibration absorber has a beam with a mass secured thereto. The vibration absorber is mounted externally to the motor, in a direction perpendicular to an axis of torsional vibration of the motor. The absorber is tuned to have a resonant frequency corresponding to the torsional vibrational frequency of the motor.
