Abstract
Piezoelectric shunt damping is new technique to damp mechanical vibrations of structures. Because of the piezoelectric effect, vibration energy is converted into electrical energy. In the attached network some part of the energy is dissipated. Switching shunts offer the possibility to adapt to varying excitation frequencies. In this paper, the damping performance of different switching techniques are calculated considering all important network parameters and non-idealities in the switching boards. Measurements on a clamped beam are performed to validate the results, and the switching techniques are applied to a squealing disc brake. It is shown that due to the piezoelectric shunt damping the sound pressure level can be reduced considerably.
