Embodiment Construction
[0012] combine figure 1 , the silicon micro-angular vibration output gyroscope of the present invention is used to measure the angular rate in the Z-axis direction. The gyroscope consists of an upper mechanical structure and a lower glass substrate. The upper mechanical structure of the gyroscope is composed of a pair of identical substructures 100, 200. The two substructures 100, 200 are symmetrically arranged left and right, and are connected to each other through the mass connection mechanism 6. At the same time, the two substructures 100, 200 are connected to the beam 3a , 3b connection. The first beam 3a is connected to the first fixed base 1a through the first group of horizontal torsion bars 2a, 2b, 2c, 2d. The second beam 3b is connected to the second fixed base 1b through a second group of horizontal torsion bars 2e, 2f, 2g, 2h. The mass connection mechanism 6 is composed of two connecting rods 6a, 6b and a connecting frame 6c. One end of the two connecting rods 6a...
