Our vibration dampener is used to minimize the effects of wind-induced Aeolian Vibration. When this type of vibration is identified (it is site specific and unforeseeable), a dampening system is used to mitigate the stress effects.
The vibration dampening system consists of a length of chain encased in a plastic tube that runs approximately two-thirds the length of the pole. This piece disturbs the harmonic cycling of the shaft (Aeolian vibrations) by touching the inside surface of the pole in a random and spiral manner. While the dampener does mitigate the stress effects of the vibration, it is not a guaranteed solve for such an occurrence.
