VIBRATORY GYRO-SENSOR USING A FLEXURAL SAME-FORM DOUBLE-MODE DISK RESONATOR

This paper deals with a new type of vibratory gyro-sensor using a flex ural same-form double-mode disk resonator with additional inertia. Thi s vibratory gyro-sensor can be supported at its center of gravity, and has a hat structure to meet, at a right angle, the axis of the angula r velocity to be measured. The principle of the basic operation and th e practical structure of the vibratory gyro-sensor are described in th e first part of this paper. In the second part of the paper the experi mental results of a prototype gyro-sensor are explained. Moreover, the modified vibratory gyro-sensor of the diaphragm type is also describe d in this paper. The results obtained proved that the disk-resonator p roposed by us operated as a gyro-sensor and showed relatively good gyr o-sensor characteristics.
