This paper investigates a passive vibration suppression system for a flexible beam using piezoelectric devices. The vibration suppression system is composed of bimorph piezo-elements (piezoelectric ceramic tiles bonded on the beam both surfaces) and shunted RL electrical network combined with the piezo-electric ceramics as inherent conductors. The result of the vibration control experiment shows that the passive vibration suppression system is practically effective. The electrical system works as a kind of dynamic damper for the mechanical system. This paper also shows that it is quite effective to design the optimal resistance, as well as the inductance, of the passive electrical network to suppress the peak gain over the resonant frequency range.
