Embedded shaking system of laser gyroscope

Abstract

The invention provides an embedded shaking system of a laser gyroscope, a shell boss structure is canceled, and a supporting boss and a shaking wheel in the prior art are integrated into a whole, so that the problem of non-uniform heat transfer between the shell and a resonant cavity is solved from the aspect of structural design, and meanwhile, the rigidity of the laser gyroscope shaking system is improved to the maximum extent; the problem that the jittering performance of the laser gyroscope is affected by inconsistent screw installation torque of the shell supporting boss and the jittering wheel is effectively avoided. According to the technical scheme, the laser gyro comprises the embedded shaking wheel, piezoelectric ceramic pieces, a disc base and a planar shell, the two side faces of each spoke of the embedded shaking wheel are each provided with one piezoelectric ceramic piece, and the two ends of each spoke of the embedded shaking wheel are each provided with one piezoelectric ceramic piece. The lower end of the embedded shaking wheel is fixedly connected with a disc base, and the disc base is fixed to the inner bottom of the planar shell.

Description

technical field [0001] The invention relates to the technical field of laser gyroscope manufacturing, in particular to a laser gyroscope embedded shaking system. Background technique [0002] In order to eliminate the influence of the blocking effect that the laser gyroscope cannot measure small angular rates, the current jitter bias technology is usually used. Since the mechanical jitter bias technology does not increase the complexity of the optical path and does not introduce cumulative errors, the machine jitter bias technology has been the most widely used. [0003] Due to the difference between the application environment of the shaking mechanism and the shell, the shaking mechanism usually uses super Invar (Invar) material with a low expansion coefficient, and the shell is made of high-strength and corrosion-resistant aviation duralumin (7075) material. It is separated from the resonant cavity by a certain distance, and the shell is usually processed with a structure...
