The purpose of this research is to develop a piezoelectric angular rate sensor with high stability. Some devices are done to realize such a sensor. (1) Design by a Electro-mechanical Equivalent Circuit Sensor characteristics of a piezoelectric angular sensor can be designed by use of the equivalent circuit proposed here. This circuit needs measured equivalent circuit constants of a piezoelectric double-resonant vibrator, and are also utilized to simulate null signal characteristics of the sensor. (2) Construction of a Angular Rate Sensor with a Wideband Frequency Characteristic In the construction, electrical tuning inductors are inserted parallelly to the terminals of a ordinal piezoelectric double-resonant vibrator. The drive-side resonant frequency need not to coinside with the detection-side one, and the sensitivity of the sensor is all equal in a wideband frequency range. (3) The electronic circuits for drive and detection of a sensor are also considered.In conclusion, null signals in a piezoelectric double-resonant vibrator must be stable and constant at a drive frequency for stabrility. As a device is considered now, this attempt will be adopted to design a angular rate sensor from now on.

本研究旨在研制一种高稳定度之压电式角速率感测器。为了实现这种传感器，已经做了一些器件。(1)用机电等效电路设计压电角度传感器的特性可以用本文提出的等效电路来设计。该电路需要测量压电双谐振振子的等效电路常数，并用来模拟传感器的零信号特性。(2)宽带频率特性角速率传感器的结构在该结构中，电调谐电感器被插入顺序压电双谐振振子的端子。驱动侧谐振频率不需要与检测侧谐振频率一致，并且传感器的灵敏度在宽带频率范围内均相等。(3)最后，对传感器的驱动和检测电路进行了分析，得出结论：压电双谐振振子的零值信号必须在一定的驱动频率下保持稳定。作为一种器件，今后将采用这种尝试来设计角速率传感器。
