摘要：

Characteristic parameters of piezoelectric ceramic have immeasurable effects on its performance. On the basis of the equivalent circuit of piezoelectric ceramic, dynamic resonance method is used to measure a series of cylindrical piezoelectric coefficients. Based on labview virtual instrument technology, an automatic measurement system with Agilent E4980A impedance analyzer is developed. The characteristics of impedance frequency response are recorded and the admittance circle is drawn. Then the major parameters including d(33) are measured automatically and the reports are generated. Finally, E-S(Electric-Strain) method is adopted to verify the reliability of the measurement results. The results showed that the dynamic resonance method had good repeatability with the standard deviation no more than 1.66%, and the test values were in accord with the E-S method.
