摘要

陶瓷的表征对超声换能器的优化至关重要。要做到这一点,我们必须确定陶瓷的功能特性:纵波的振动速度kt =耦合系数:表明陶瓷将电能转化为机械能的能力介电常数,电和机械损耗声阻抗,电学测量使我们能够确定可用陶瓷的功能特性。由于数字模拟器(KLM),我们能够改进由此获得的结果。

Characterization of PZ27 and PZ52 Piezoceramics from Electrical Measurements
The characterization of ceramics is essential for the optimization of ultrasonic transducers. To do this we must determine the functional properties of ceramics which are: speed of vibration of longitudinal waves kt = Coupling coefficient: indicates the ability of the ceramic to transform electrical energy into mechanical energy the dielectric constant electrical and mechanical losses acoustic impedance The electrical measurements allowed us to determine the functional properties of the ceramics available to us. We were able to refine the results thus obtained thanks to the digital simulator (KLM).
