The invention discloses a cylindrical shell Coriolis vibratory gyro based on electrostatic excitation and detection, and relates to the technical field of inertial devices. The cylindrical shell Coriolis vibratory gyro based on electrostatic excitation and detection includes a cylindrical shell resonator, an electrostatic excitation and detection integrated top cover, a gyro sealing shell, a gyrobuffer circuit board, a gyro electrode outgoing line and a gyro support outer wall; the electrostatic excitation and detection integrated top cover is fixedly arranged below the gyro buffer circuit board in a parallel manner; the electrostatic excitation and detection integrated top cover is fixedly connected with the gyro buffer circuit board through the gyro electrode outgoing line; the cylindrical shell resonator is fixedly arranged below the electrostatic excitation and detection integrated top cover; the gyro support outer wall is a hollow cylinder structure, and the gyro support outer wall coaxially sleeves between the lower surface of the electrostatic excitation and detection integrated top cover and the upper surface of the bottom surface of the cylindrical shell resonator; and the gyro sealing shell is arranged outside the gyro support outer wall. The cylindrical shell Coriolis vibratory gyro based on electrostatic excitation and detection has the advantages of simple structure, high vibration Q value, achieving of the high measurement precision through using an electrostatic excitation and electrostatic detection manner, and easiness in processing and assembling.
