Abstract
The numerical simulation and experimental method are adopted to analyze the piezoelectric vibration control of the simplified autobody beam structure. The autobody beam structure is simplified as a beam fixed at both ends. The finite element model of beam structure with piezoelectric patches is established. The static analysis and modal analysis is conducted by the piezoelectric analysis of the finite element analysis software. The proportional and proportional-derivative control methods are studied in the piezoelectric active vibration control analysis for the simplified beam structure. The experimental system is established to obtain the vibration control effectiveness of the beam structure. The experimental results show that the type of two ends patching beam has more effective vibration control ability than the central patched beam.
