Title: Angular velocity detection method and vibration gyro
Inventor: MAENO TAKASHI
IPC: G01C19/56
Filed: 1993-04-16
Abstract: PURPOSE:To simplify a structure and enable angular velocity around a multishaft to be detected, regarding a vibration gyro where a vibration is excited on a vibrator and angular velocity generated around a shaft is detected. CONSTITUTION:Vibratory elastic bodies 1 and 2 are jointed to each other, thereby forming a large diameter section at the upper and lower ends of a shaft section having small diameter. Also, a plurality of piezoelectric elements 3 composed of a piezoelectric element to excite and detect a bending vibration on X-Z and Y-Z planes, and another piezoelectric element to excite and detect a torsional vibration around a Z-axis, are stacked, clamped and fixed to the jointed section via an electrode plate. Three modes of vibrations are thereby excited and detected. When a torsional vibration is applied around the Z-axis and angular velocity is generated around the X-axis or the Y-axis, the bending vibration concerned is detected and angular velocity is detected. Also, when the three modes of vibrations are selectively generated in a time series, angular velocity around three axes can be detected.
