Abstract

The invention discloses a split-type umbrella-shaped mechanical shaking device for a laser gyroscope, which includes a shaking unit and a laser gyroscope bearing unit; the laser gyroscope bearing unit includes a triangular stand, and the center of the triangular stand forms a boss, and the boss is evenly spaced with three A first fixed block, each first fixed block is provided with a screw hole, and each first fixed block cooperates with the screw and the screw hole to fix the laser gyro resonator cavity, and the boss is located at the center of the triangular pedestal to open a first hole , the three corners of the triangular pedestal are provided with second openings, the shaking unit includes the first shaking ribs and the second shaking ribs connected in turn along the direction of the center of the ring, the shaking unit cooperates with the fixed laser gyro carrying unit through the through hole . The split umbrella-shaped mechanical shaking device of the laser gyroscope of the present invention improves the accuracy of navigation measurement while reducing volume and cost.

Description

technical field [0001] The invention belongs to the technical field of inertial navigation, and in particular relates to a split-type umbrella-shaped mechanical shaking device for a laser gyroscope. Background technique [0002] At present, due to the continuous expansion of the application field of inertial navigation technology, its application in military, civilian, interstellar spaceflight, scientific exploration and other fields is also becoming more and more extensive. From a structural point of view, an inertial navigation system is usually composed of an inertial measurement device, a computer, and a controller. The inertial navigation device also includes a gyro combination and an accelerometer. The resonant cavity of the gyroscope and the control circuit are used to measure the angular motion of the object in three axes, and cooperate with the accelerometer to transmit the position and motion information to the navigation computer, so as to realize the navigation w...
