Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0026] Hemispherical resonator gyroscope is a kind of Gothic vibrating gyroscope with inertial navigation level performance. It adopts axisymmetric or approximately axisymmetric resonator. The main formation, that is, the four-wave antinode standing wave 10 natural frequency cracks, causing the standing wave to precess both relative to the shell and relative to the inertial space, and its precession angle is inversely proportional to the rotational angular velo...
