Abstract

The invention discloses a split type umbrella mechanical shaking device for a laser gyro, and the device comprises a shaking unit and a laser gyro carrying unit, wherein the laser gyro carrying unit comprises a triangular gantry, the center of the triangular gantry forms a boss, three first fixing blocks are evenly spaced on the boss, each of the first fixing blocks is provided with a screw hole and is fixed with the screw hole through a bolt to fix a laser gyro resonant cavity, the position of the boss located at the center of the triangular gantry is defined with a first opening, second openings are formed at three corners of the triangular gantry, the shaking unit comprises a first shaking rib and a second shaking rib connected in a direction along the center of the circular ring, and the shaking unit fixes the laser gyro carrying unit through a through hole. The split type umbrella mechanical shaking device for the laser gyro provided by the invention improves the accuracy of navigation measurement while reducing the 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...
