Abstract
This paper presents numerical analyses and a physical experiment on
efficiency of different shapes and material composition of piezo actuators
on vibration reduction. For this purpose numerical models of a plate
clamped on all sides with piezo actuators attached were developed. The
elements used were either standard homogeneous elements or the proposed
two-part elements with different material composition for inner and outer
part of piezo ceramic. Numerical analyses were performed using ANSYS
software
