The Effect of Rayleigh Damping on the Efficiency of Passive Vibration Suppression Using Piezoelectric Elements

Abstract A numerical simulation has been carried out to evaluate the effect of Rayleigh damping on the efficiency of passive suppression of free and forced harmonic vibrations of a thin plate using piezoelectric element connected to a passive electric circuit of different configurations. The solution is constructed using a finite element algorithm, which is developed in the context of the proposed mathematical formulation. It has been found that the efficiency of the considered method of vibration damping decreases with increasing contribution of another dissipative mechanism existing in the system.
