Abstract
A new setup for the prospective investigation of the active damping properties of magnetostrictive (MST) actuators has been realized. A dynamical finite element analysis has been carried out to meet the design requirements concerning the eigenvalues spectra and the mode shapes of the setup: experimental and numerical results match satisfactorily. The setup has given a clear evidence of the damping capabilities of a MST actuator developed by our group and utilized as a compensator of external harmonic excitations.
