Abstract
The invention relates to a vibrating gyroscope comprising vibrating cylinder (1) that is magnetically or electrostatically excited. Regularly distributed masses (19) designed to lower the vibration frequency of said cylinder are arranged thereon. The inventive gyroscope is much more accurate than conventional gyroscopes and can be produced easily at low cost. The invention can be used to measure angular rotation or angular speed.
Claims10
Vibrating gyroscope comprising:
- a thin wall hollow vibrating cylindrical element having a bottom, a foot centered on said bottom, an open extremity, and at least eight vibrating masses spaced evenly on said element and located close to said open extremity said masses forming excess thickness on said vibrating element so as to obtain a reduced resonance frequency of said vibrating element, said vibrating element further comprising excitation means for generating vibrations on at least one point of the vibrating element so as to have appear on said vibrating element vibration modes able to be modified under the effect of an angular rotation speed, and means for detecting said vibrations and placed so as to be able to detect said vibration modes.
