The performance of piezoelectric-based damping and vibration control techniques has been studied and analyzed extensively under impulse response or harmonic steady state conditions. Considered here is their performance when subjected to an excitation whose frequency is close to a structure's resonance frequency but varies sufficiently quickly to preclude a harmonic analysis. Although a rapidly-varying excitation frequency will reduce the peak response amplitude, additional vibration reduction is often desired. The current research investigates the performance of several common passive and semi-active (state switching) vibration reduction techniques. In many cases, particularly for high electromechanical coupling, a system provides sufficient vibration reduction to approximate a steady state condition. Special attention is paid to turbomachinery bladed disks and the feasibility of implementing a particular vibration reduction approach. Semi-active switching approaches are more robust for vibration reduction of multiple frequencies than passive systems which require optimal tuning to the excitation condition. State switching, synchronized switched damping, and resonance frequency detuning provide the most realistic embedded package. Of these three approaches, synchronized switched damping delivers the greatest performance, although all provide significant vibration reduction. With far fewer and less stringent switching requirements, resonance frequency detuning requires significantly less power than other semi-active approaches.
