Geometrically compensated (100) SCS mode-matched vibratory ring gyroscope

A geometrical compensation design method in (100) single crystal silicon (SCS) vibrating ring gyroscope (VRG) has been proposed in order to decrease frequency splits (∆f) caused by the anisotropic in-plane Young’s modulus (E) and realize mode-matching. The FEA simulations and experimental results demonstrated its effectivity to decrease ∆f thus realize mode-matching.
