The Influence Analysis of Geometric Parameters on Piezoelectric Vibration Control

The finite element method is adopted to simulate the vibration control effectiveness of autobody thin-walled structure by using the piezoelectric patches. The geometric parameters of thickness and area are chosen as the influence factors to analyze the control effectiveness of piezoelectric vibration control system. The simulation results show that the base metal thickness, piezoelectric patch thickness and the area of piezoelectric patch are main parameters and influence the control effectiveness obviously. The influence rules of these geometric parameters are obtained.
