Piezoelectric Vibratory Gyro-Sensor Using a Trident-Type Tuning Fork Resonator

Abstract

This paper deals with a piezoelectric vibratory gyro-sensor using a trident-type tuning fork resonator. It is expected that the vibratory gyro-sensor has a high stability as an angular rate sensor. In order to develop such a gyro-sensor, the authors have focused on applying a trident-type tuning fork resonator that is independent of its support condition. In this paper, the vibrational analysis of a trident-type tuning fork resonator and its measured characteristics as an angular rate sensor are described.
