“…Figure A shows the short circuit condition, in which after removal of driving force the current and vibration velocity decay. Similarly, after imposing the open circuit condition using a mechanical relay, the voltage and vibration displacement decays, however, at antiresonance depending on the driving period and frequency jump a DC bias voltage can be seen …”

A new methodology is proposed to measure the dielectric constant and loss of a piezoelectric at the resonance frequency range based on the burst excitation method. Using a k 31 type soft PZT rectangular specimen, we investigated the "force" and "voltage" factors carefully under the short-and open-circuit conditions of the burst method, in terms of the ratio of the ring-down current and voltage with the plate end vibration velocity and the displacement, and their phase lags. We provide the obtained material properties, including loss parameters, in particular, dielectric properties at the resonance frequency range.burst mode, dielectric loss, ferroelectric materials, high power, piezoelectric material/properties

“…The short-circuit current behaves like the vibration velocity. An open-circuit voltage, containing a DC part and an AC part, in transient state at input terminals of a BLT transducer has occurred immediately after an AC voltage connected to the transducer is disconnected [7], [8]. The DC part or the AC part has an exponential decay envelop with a form of e -t/τ .…”

This paper investigates characteristics of electrical tranisent responses, including short-circuit currents and opencircuit voltages, at input terminals of a bolt-clamped Langevin type (BLT) transducer under different one-shot hitting drive conditions by theretical and experimental results. The characteristics contain maximum short-circuit currents, maximum open-circuit voltages, oscillation frequencies, time constants and dissipation energies. In doing so, an equivalent circuit model of the BLT transducer for deriving the tranisent responses and their characteristics is proposed first. Then, a driving and mesuring system, including an one-shot force generator, an oscilloscope and a current sensor, for getting experimental results of the characteristics is constructed. The experimental results are compared with the theretical results. Finally, effects of magnitudes of one-shot hitting forces on the characteristics of the tranisent responses for the BLT transducer under different drive condtions are discussed.
