AXIALLY SYMMETRIC CORIOLIS VIBRATORY GYROSCOPE (VARIANTS)

摘要

Coriolis vibratory gyroscope includes a thin-walled resonator, fastened centrally on a stem located within the resonator; with 4nk holes in a wall of the resonator and arranged around the stem, where “k” is integer, “n” is order of vibration modes, and the angle between adjacent holes is “π/2nk”. The stem is rotationally symmetric and is fastened on a base; electrodes are arranged on the wall for excitation and measurement of vibration modes, with leads passing from the electrodes through the holes; the base has a seating for the resonator stem, and leads pass from the outside of the base through it, the leads being electrically-insulated and sealed relative to the base; the leads which pass through the base are connected to the leads which pass from the electrodes, allowing signals to pass from outside the base, through the base, through the holes in the resonator wall and to the electrodes.

1. An axisymmetrical Coriolis vibratory gyroscope, comprising:
a thin-walled resonator of hemispherical or cylindrical or toroidal shape, fastened centrally on a stem located within the resonator; a wall of the resonator having holes arranged around the stem, a number of holes based on “4nk”, where “k” is an integer, “n” is an order of vibration modes of the thin walled resonator, and an angle between adjacent holes is equal to “π/2nk”; wherein the stem is rotationally symmetric about its longitudinal axis and is fastened on a base; electrodes are arranged on the resonator wall or alongside the resonator wall for excitation and measurement of two vibration modes, with leads passing from the electrodes through holes in the resonator wall; the base includes a seating for the resonator stem, and leads pass from the outside of the base through the base, the leads being electrically-insulated and sealed relative to the base; and the leads that pass through the base are connected to the leads that pass from the electrodes, thereby allowing signals to pass from outside the base, through the base, through the holes and to the electrodes.
