Eight-Point Model of the Hemispherical Resonator Gyro

Yuri Zhbanov

Abstract:	We consider a simple mechanical model of the hemi- spherical resonator gyro. This model enables us to show what makes the device sensitive to the rotation of the base. In this model, the resonator consists of eight mass points connected in series by rigid mass-free rods, with an ideal (friction-free) elastic joint being located at each mass point. One vibratory mode established in this sys- tem is a standing wave in a contour at which lie all eight mass point. The inertial forces due to the rotation of the base are show to change the orientation of the standing wave in the contour. We clear up condition needing for ideal working the device in the time of basis turning with angular acceleration.
