Integration of piezoceramic components in aluminum high pressure die castings

High pressure die casting is one of the most advanced processes to create high quality aluminium goods. Complex shapes and thin walled component sections provide the casting technique with advantages for high unit production. As many HPDC products are applied in transport vehicles, vibrations can occur due to lightweight construction. In this work piezoelectric modules in the casting add an adaptronic function to the component assembly to influence the vibrations in the system. Contrary to an application on the component surface, the functional module is protected against external influences and force/form-fitted in the casting. A hybrid fixing system using Al-sheets is presented to assure the damage-free integral cast of layered piezoceramic modules.
