Abstract


Passive vibration shunt control using piezoelectric materials and an electrical network can remove vibration energy from structures. However, the vibration shunt control efficiency relies on the optimization of the vibration energy transfer between a structure and a Lead-Zirconate-Titanate piezoelectric ceramic material. We present an analytical study of a parallel resistor-inductor piezoelectric vibration shunt control on a beam structure using Hamilton's principle and Galerkin's method. The influence of the material's mechanical property on vibration energy transfer between the structure and the Lead-Zirconate-Titanate is discussed. The results of the vibration shunt control with various materials obtained from numerical modeling and experiments are discussed and corroborated.
