Changing the eigenfrequency spectrum using passive vibration absorbers

Using a substructure coupling technique the problem of assigning anti resonances is reformulated as a pole placement problem which can be analyzed in a more general framework. A possible approach to create these points of zero vibration is by attaching passive undamped vibration absorbers. As this approach is sensitive to changes in the excitation frequency, a robustness measure is proposed. Based on this measure, a better understanding is provided regarding the attachment location of the absorber and the absorber mass.
