Undamped vibration absorber
Web1 Jan 2008 · Dynamic vibration absorbers can be used for passive control of narrowband vibration. As described in the classical textbooks on dynamic vibration absorber [1], [2], [3], an undamped dynamic vibration absorber is an auxiliary mass–spring system which, when correctly tuned and attached to a vibrating body subject to a harmonic excitation, … Web28 Apr 2024 · Optimal vibration absorber parameters can easily be derived without complicated calculations for undamped and damped structures using Tables 3 and 5. In investigating the effects of the indicators on amplitude magnification factor for undamped structures, the mass ratio is of great importance.
