Piezoelectric-based Vibration Control in Composite Structures

ct This paper relates to vibration control using passive electrical shunt circuits. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate (PZT) piezoelectric ceramic material. The problem is further complicated by the material composition of the substrate or host material the PZT is coupled to. In this paper, an analytical study of a parallel resistor-inductor piezoelectric vibration shunt control on a composite beam structure is presented. The influence of the geometry size and material property on the mechanical strain produced in the PZT is discussed.
