Design of an adaptive–passive dynamic vibration absorber composed of a string–mass system equipped with negative stiffness tension adjusting mechanism
Mustafa A. Acar,Cetin Yilmaz +1 more
TL;DR: In this article, a new adaptive passive dynamic vibration absorber (DVA) design is discussed, which is composed of a string under variable tension with a central mass attachment as an undamped DVA and a negative stiffness mechanism as a string tension adjustment aid.

H∞ and H2 optimizations of a dynamic vibration absorber for suppressing vibrations in plates
Y.L. Cheung,Wai On Wong +1 more
TL;DR: In this paper, an analytical solution to the H∞ and H2 optimization problems of DVA applied to suppress random vibrations in plate structures is presented. But the analytical results show the usefulness of the optimization solutions in comparison to solutions suggested by other researchers based on other approaches to the problem.

Dynamic vibration absorbers for vibration control within a frequency band
Cheng Yang,Deyu Li,Li Cheng +2 more
TL;DR: In this paper, the use of dynamic vibration absorbers to control the vibration of a structure in both narrow and broadbands is discussed, and the coupling properties due to the introduction of the absorber into the host structure are analyzed; and the control performance of the vibration absorber in different control bandwidths is examined with respect to its damping and location.

Sweeping shunted electro-magnetic tuneable vibration absorber: Design and implementation
Emanuele Turco,Paolo Gardonio +1 more
TL;DR: In this article, a time-varying RL-shunt is used to harmonically vary the stiffness and damping properties of a Tuneable Vibration Absorber so that its mechanical fundamental natural frequency is continuously swept in a given broad frequency band whereas its mechanical damping is continuously adapted to maximize the vibration absorption from the hosting structure where it is mounted.
