How to reduce vibration of a fixed beam?

  1. Feb 17, 2016 #1
    If I want to reduce the vibration of a beam fixed at one end, under a distributed load, does anyone know what this would involve? In the textbook, there is the idea of having a second system consisting of a mass-spring combination to reduce the vibration of the primary system.
    But I can't find any real life pictures of this setup, so I don't know what this would look like. I was wondering if someone could explain a little more about the situation or other options.

    You may be talking about a mass-flexible rod system called the Stockbridge Damper that is sometimes used on cantilevered highway signs near the free end to offset (dampen) the vibratory oscillations. Google it for more info.
