Den Hartog criteria

  1. Dec 9, 2014 #1
    1. The problem statement, all variables and given/known data
    I have been searching online but I am unable to find a site that explicitly states the Den Hartog criteria for a tuned mass damper.

    What is the Den Hartog criteria?

    2. Relevant equations

    3. The attempt at a solution

    It has
    \mu = m/M
    Is ##M## total mass of the system prior to the damper or is the total mass plus the damper mass of m?

    Look at figure 1, it shows M and m are distinct masses so M is not in fact M+m

    I am not sure on how I would design a tuned mass damper from the paper though. I am trying to design one for a system with ##M = 55## kg and a tuned mass damper weighing ##5.5## kg. The natural frequency of the system is ##\omega_n = 12.061## and the forcing function has ##\omega = 183.26##.
