Embodiment Construction

[0040] figure 2 One embodiment of a vibratory gyroscope 1 according to the invention is shown.

[0041] The gyroscope 1 includes a substrate 2 as a base. The gyroscope 1 also includes a plurality of vibration control and processing modules 18 , which will be described below, placed at least partially in the base 2 . Usually, these modules 18 are arranged on an electronic control card integrated in the lower part of the base 2 and covered by a protective cap.

[0042] The gyroscope 1 also includes a resonance device 3 . The resonance device 3 comprises a generally cylindrical body 4 ending in a distal face 5 on the side opposite the base 2 .

[0043] The resonance device 3 is usually a metal piece.

[0044] In particular, the face 5 includes at least one through hole 13 . exist figure 2 In an embodiment, the surface 5 includes a plurality of through holes 13 .

[0045] The gyroscope 1 also includes a plurality of piezoelectric elements 10 placed in contact with the res...

Abstract

The invention relates to a vibrating gyroscope (1), characterised in that it comprises a base (2), a resonator (3) comprising a body (4) of generally cylindrical shape terminating in a distal face (5), to the side opposite the base (2), said face (5) comprising at least one through hole (13), a plurality of piezoelectric elements (10) placed in contact with the resonator (3), vibration control and processing modules (18) arranged at least in part on the base (2), and at least one electrical connection (15) passing through the body (4) of the resonator (3) via said hole (13), and electrically connecting said modules (18) of the base (2) and the plurality of piezoelectric elements (10) for controlling and measuring the vibration of the resonator (3).

Description

technical field [0001] The present invention relates to vibrating gyroscopes and methods of making such gyroscopes. Background technique [0002] Vibrating gyroscopes are currently used in many fields due to their robustness, low power consumption, and fast performance. [0003] These gyroscopes include resonant devices that can take various forms, such as a bell or tuning fork. [0004] The invention more particularly relates to a resonant device comprising a substantially cylindrical body. [0005] The axis z is usually specified as the axis of the cylinder, and the axes x, y are set on a plane orthogonal to the axis z. [0006] As is known, the vibrating resonator itself is preferably deformed elliptically and has four vibration antinodes in the x, y plane arranged regularly on the circumference of the cylinder. figure 1 The first vibration mode 53 , 57 of the resonator device relative to the rest state 54 at two given instants is shown in . The resonant device change...
