The transient voltage generated directly across a thickness-mode piezoelectric transducer excited by an external voltage source has been related in reference [1] to the width of the initial pulse in the received ultrasonic signal display and hence to the width of the dead zone of detection.

The transient voltage generated directly across a thickness-mode piezoelectric transducer excited by an external voltage source has been related in reference [1] to the width of the initial pulse in the received ultrasonic signal display and hence to the width of the dead zone of detection. One dimensional theory predicts that this "induced voltage" is approximately the superposition of a decaying high frequency oscillation, of frequency close to that of the radiated ultrasonic wave, and a steep exponential rise, resulting principally from the charging of the clamped capacity of the transducer by the applied transient voltage.

在文献[1]中,我们曾经讨论了厚度模压电换能器在受到外电源的激励时直接产生的瞬变电压。曾指出这个电压同换能器接收超声信号时显示出的始脉冲宽度有直接联系,因而也和检测盲区的大小有直接联系。根据一维理论,这个应电压近似地是衰减的高频振荡,其频率接近于换能器所辐射声压的频率,叠加在一个指数曲线上,指数曲线系起源于外加瞬变电压对换能器钳定电容的充电。 本文给出了在阶跃电压的激励下具体计算应电压的步骤,并分析了几项结构参量对应电压的各自影响。理论采用了梅森(W.P.Mason)等效电路模型。这些参量是:(1)负载或背衬材料的声阻抗率,(2)压电片的机械Q值,(3)刚玉保护膜的厚度,(4)并联线圈的电感。 理论计算结果表明: (1)在轻负载或轻背衬时,高频振荡部分大而拖长;在重负载或重背衬时,则这部分小,并且较快地衰减。 (2)对于同一种压电陶瓷,当约Q<100,降低Q值会减小高频振荡部分的幅度,而当约Q>100,改变Q值并不显著地影响高频振荡。 (3)在轻负载的条件下,增加保护膜的厚度会加大高频振荡的幅度;在重负载的条件下,当负载的声阻抗率匹配或接近匹配压电陶瓷时,保护膜对应电压的影响不明显。 (4)从并联电感的初步探...
