Abstract: | In 1], we have studied how the coupling between the working and beam type vibrations of the resonator affects the hemispherical
resonator gyro operation. We show that such a coupling arises if the resonator is unbalanced. The beam type vibrations are
considered as translational displacements of the resonator hemisphere in the plane orthogonal to the symmetry axis. In the
present paper, we take into account the fact that the hemisphere translational displacement is accompanied by its rotation
about the axis perpendicular to the displacement line. We show that in this case a more accurate balancing of the resonator
is required to eliminate the coupling between the two vibration modes. |
