Abstract:
A ring gyroscope structure with central spring structure that prefers prefers 2θ-modes and makes them low in frequency. The flexing resonance modes that tend to couple to external mechanical excitation are clearly higher that the 2θ-modes. The described structure is thus very robust against external mechanical shocks and vibrations.
