压电陶瓷移相器连续驱动的时间间隔和每一时间间隔之间的驱动步进电压, 是影响相移标定精度的重要因素.时间间隔过长,不足以克服外界干扰因素的影响;采集卡最大采集速率限制着时间间隔又不能过短.同样, 压电陶瓷驱动步进电压太大, 采样点数太少;采集卡的分辨率和运算时间又限制着驱 动电压步长不能太小.综合考虑上述...
PZT 基压电元件（PZT-based piezoelectric devices）指的是借助铅锆钛酸钡（Pb(Zr,Ti)O?，简称 PZT）这种陶瓷材料的压电效应制成的元件。下面来讲讲 PZT 基压电元件在振动测量以及转子故障检测方面的应用。PZT 陶瓷属于有压电效应的材料，一旦受到外力或者电场，就会出现形变或者产生电荷。依据这个道理，PZT 基的压...

Using this value and combining the measurement and the modeling of the cantilever displacement amplitude at a given voltage, we extract PZT d31 piezoelectric coefficient as being 165±25 pm/V; which is among the highest values ever published for PZT thin films. It is worth noting that d31 ...
Fig. 3 Dynamic displacement measurement system for piezoelectric actuators 3 结果和讨论 对于受恒定外加应力的压电陶瓷单片,当在垂直于其厚度方向(极化方向)的二表 面加上一电压, 在只考虑压电形变为线性形变时,由压电方程可知,压电陶瓷单片沿纵 向厚度方向产生的位移Δll表示为 ...
