Abstract


Piezoelectric modules are integrated in structural aluminum components (AlSi9Cu3(Fe)) using high-pressure die casting for damping purposes. Investigations using X-ray analysis indicate a damage free integration and good casting quality despite very harsh casting conditions. FE simulations provide information about the mode shapes of the casting and could be confirmed by investigations using a 3D laser scanning vibrometer (LSV). Frequency sweeps show that many modes are stimulated by applying voltage to the piezoelectric module. It is demonstrated, how an actively induced vibration signal in the casting is reduced by creating a phase-shifted counteracting vibration with the help of the integrated module.
