Abstract

The invention discloses a calibration method and a calibration device of a gyroscope angular motion measurement system. The calibration device comprises a calibration frame, a main shaft, a driving device, an angular vibration acquisition system, an angle reflector, an interference mirror, a laser interferometer and a computer. The calibration method comprises the steps of: controlling an angularvibration table to perform angular vibration according to a set motion angle signal, and acquiring angle rotation data by means of the angular vibration acquisition system and transmitting the angle rotation data to the computer; feeding back a motion angle signal to a servo control system to control a servo motor to move reversely, and directly measuring angle deviation between an angle reflectorand an initial position by means of the laser interferometer; synthesizing the angular rotation data and the angle deviation into a rotation angle value, and calibrating the angular vibration table;and S6, repeating the above steps to complete calibration of the angular vibration table in the whole angular vibration process. According to the calibration method and the calibration device, the problem that the gyroscope angular motion measurement system is difficult to calibrate on site can be solved.

Description

technical field [0001] The invention relates to a calibration method and device for a gyroscope angular motion measurement system, and belongs to the field of testing inertial devices such as gyroscopes. Background technique [0002] Gyroscope is a high-speed revolving body's moment of momentum sensitive housing relative to space around the angular motion calibration device orthogonal to the axis of rotation, and has been widely used in civilian and military fields. The gyroscope angular motion measurement system is the main equipment for measuring the dynamic characteristics of the gyroscope. The key equipment is the angular vibration table, which can accurately simulate the angular motion state of the gyroscope. The accuracy of the angular motion value is directly related to the dynamic characteristics of the gyroscope. Therefore, it is very important to calibrate the gyroscope angular motion measurement system. [0003] At present, the calibration of the gyroscope angula...
