Abstract

The invention discloses a sidewall piezoelectric-driven ring vibrating gyroscope and its driving and detection method. The gyroscope comprises a resonant ring 1, a supporting spring 2, an anchor point 3 and a piezoelectric electrode 4. The piezoelectric electrode 4 is fixedly connected on a sidewall of the supporting spring 2, close to the anchor-point end; and the piezoelectric electrode 4 is used for excitation and detection of deformation of the resonant ring. The whole structure is simple and the detection method is convenient to operate. In comparison with a present ring vibrating gyroscope with a piezoelectric electrode arranged on the upper surface, the sidewall piezoelectric-driven ring vibrating gyroscope has characteristics of large driving displacement, high detection sensitivity, low energy consumption, small volume, impact resistance and the like.

Description

technical field [0001] The invention relates to a ring vibrating gyroscope driven by side wall piezoelectricity and its driving and detection methods. Background technique [0002] The ring vibrating gyroscope uses the inertial effect of the elastic wave in the resonant ring to realize the angular velocity measurement. Ring vibrating gyroscopes have the unique advantages of solid wave gyroscopes, such as high precision, low energy consumption, short preparation time, wide operating temperature range, strong resistance to ionizing radiation, good shock resistance and vibration resistance, and long service life. The development and application prospects are extremely broad. [0003] The working principle of the ring vibrating gyro is: through a certain driving method (electromagnetic drive, electrostatic drive or piezoelectric drive, etc.), the resonant ring is excited at a specific frequency such as figure 1 The first mode shown (i.e., the driving mode) is represented by fi...
