Abstract

The invention discloses a silica-based double-gimbal dynamical tuned gyroscope rotor body structure comprising an inner ring, a rotor and two independent gimbals, wherein the inner ring, the rotor and the gimbals are hollow cylinder structures, the inner ring is fixedly connected with the motor rotor, and are arranged in the rotor, and the gimbals are arranged between the inner ring and the rotor, and are respectively connected with the inner ring and the rotor by an internal torsion bar and an external torsion bar. The invention further discloses a processing method of the silica-based double-gimbal dynamical tuned gyroscope rotor body structure. According to the silica-based double-gimbal dynamical tuned gyroscope rotor body structure disclosed by the invention, the influence caused by the twice frequency angle vibration of the single-gimbal can be effectively eliminated, and the gyroscope precision can be improved.

Description

technical field [0001] The invention relates to the design field of micro-electromechanical gyroscopes, in particular to the rotor body structure and processing method of silicon-based double balance ring dynamic adjustable gyroscopes. Background technique [0002] The silicon microgyroscope manufactured by microelectromechanical technology has the advantages of small size, light weight, low cost, high reliability, low power consumption, and mass production. It can be widely used in aviation, automobiles, medical care, photography, electronic consumption, etc. field and has broad application prospects. At present, it has become an important direction for the development of inertial navigators. Many colleges and research institutes at home and abroad are conducting research on MEMS gyroscopes. [0003] An electromechanical gyroscope developed in the 1960s on the traditional dynamic harmonic gyroscope. It is a two-degree-of-freedom gyroscope that suspends the gyro rotor with...
