Vibrating-beam gyro of vibrating-beam-type dual-cantilever-face bracing structure

The invention discloses a vibrating-beam gyro of a vibrating-beam-type dual-cantilever-face bracing structure, which comprises a gyro vibrating beam and piezoelectric sheets, wherein the gyro vibrating beam is provided with nodes on two ends and has a rectangular section, and the piezoelectric sheets are respectively bonded and fixed on four surfaces of the gyro vibrating beam. The vibrating-beam gyro is characterized in that the two vibrating nodes of the gyro vibrating beam are respectively and fixedly provided with bracing faces. Experiments show that because face-structure bracing vibrating beams are adopted for the vibrating-beam type gyro disclosed by the invention on the basis that the advantages of the traditional dual-node bracing gyro are maintained, the shock-resistant vibration value of the vibrating-beam gyro is improved to the gravity acceleration of 105 orders of magnitude, and the expansion of the application range of the dual-node vibrating beam gyro is greatly promoted. Meanwhile, the vibrat
