Fabrication method for series production of sheet metal parts with integrated piezoelectric transducers

The paper presents a high volume compatible production method for the fabrication of sheet metal parts with integrated piezoelectric transducers. The functionality of the integrated piezomodule is shown on a wing assembly, consisting of two sheet metals shaped with roll bending and three point bending operations. The stimulation of the structure is performed with a shaker, the reduction of the acoustic noise was realized with the integrated piezomodule and monitored with vibrometer measurements. Impedance measurements were performed for health monitoring of the multiple bolted joint. Furthermore, a simulation of the structure was used for the determination of resonance frequencies. The results show a good correlation between experiment and simulation.
