Optimal parameters of linear dynamic vibration absorber for reduction of torsional vibration

This paper presents three analytical methods to determine optimal parameters of the passive mass-springdisc dynamic vibration absorber (DVA), such as the ratio between natural frequency of DVA and shaft, damping ratio of DVA. The original model presented by Den Hartog, Luft and Warburton are solved and has shown in good agreement. Three analytical methods is then adopted for torsional shaft model.
