Summary:This paper presents a study on the optimum design of a distributed actuator that is introduced in order to suppress the multimode vibration of a flexible structure. The piezoelectric bimorph cell installed as a distributed actuator is driven so that it suppresses the transient vibration of a flexible cantilever. The actuator is designed with the inclusion of the idea of dynamic compliances, of which is the compliance of the beam driven by a distributed actuator, while the other is the oscillation compliance of a beam subjected to a sinusoidal fluctuation at its base. It is found that a piezoelectric actuator to supress the multimodal vibration can be designed systematically with the use of the compliances proposed here.
