Vibration Suppression Systems

Vibration Dampeners inside the SteadyMax Poles

What makes our security camera poles so rigid and steady in any wind condition? We here at StrongPoles install two separate Vibration Dampener Systems in our SteadyMax Poles that work to stop both modes of vibration in their infancy. 

 Typically when you think of a pole shaking in the wind, it is from very high winds. However, most destructive pole vibration actually happens in much slower winds (10-30 mph). As the wind frequency nears certain speeds and directions or interacts with the local topography or nearby structures, this causes a vortex as it passes by the pole. As this vortex reaches a frequency that resonates with the pole, vibrations can occur that causes the pole to shake – either at the top of the pole or mostly in the middle of the pole. These vibrations, which are a natural phenomenon, and are usually site-specific, are not due to any fault in the pole design, material or workmanship, can be described like this: 

  • First Mode Vibration: This is when you see the top of a pole shaking back & forth, similar to a diving board.
  • Second Mode Vibration: Occurs around the midpoint of a pole, and acts more like a guitar string.

Here is how that Vibration Suppression system works. The Dampener at the top of the pole is an impact style design that mainly introduces an impact opposite of the vibration oscillations that interrupt the vibration and shuts it down. The second Dampener is mounted closer to the midpoint of the pole and counteracts the higher frequencies found in Second Mode vibration, in much the same way as the First Mode Dampener. Together, these two systems go after any sway and vibrations that may happen and returns the pole to the stable camera platform it is intended to be.
