摘要:
The invention relates to gyroscope equipment. The axially symmetrical Coriolis vibratory gyroscope comprises a thin-walled resonator with a hemispherical or cylindrical or toroidal form, said resonator being fixed at the center to a support and being formed with openings in that wall of the resonator which is located around said support, the number of openings being determined on the basis of the formula 4nk, where k is an integer, n is the order of oscillation modes, and the angle between two neighboring openings is equal (I), wherein said support has a symmetrical form along the longitudinal axis thereof and is fixed to a base, solenoids and electrodes are positioned on the wall of the resonator or next to the resonator for exciting and measuring two oscillation modes, the constant amplitude of one of the modes thereof being intended for monitoring a secondary oscillation mode which is sensitive to Coriolis forces, and the base is provided with a seat for the support of the resonator and with electrically insulated hermetically sealed leads which pass outwards via the base and are passed through the openings in the wall of the resonator for connection to elements of an electronics board.
