Abstract
Piezoelectric shunt damping is an active field of research since many years. A broad range of electrical shunts for different applications have been proposed. Switching networks are capable to adapt to different excitation frequencies. In the SSDI - technique (synchronized Switch Damping on Inductor) the switch is triggered by the signal of an additional sensor and connects an inductance - resistance - network to the electrodes of the piezoceramics. In the SSDV - technique, an external voltage source is added in order to actively increase the damping performance, but stability problems may arise. In this paper, the different switching techniques are compared regarding their damping performance. Both the stationary and the transient behaviour are discussed, and the influence of the network parameters is determined. Analogies to mechanical damping elements are pointed out. Measurements on a test rig validate the theoretical results.
