Abstract

An alignment method for a radial magnetic suspension stator element of a gyroaccelerometer includes a turntable and a cross slide table. A stator tool is arranged on the turntable and connected with an inductance tester. An adjustment mechanism is arranged on the cross slide table. The adjustment mechanism is provided with a torque sensor. After adjusting a pitch angle, a yaw angle and a center height of a rotor tool, by passing a stator element through a rotor element, variation on inductance values of the stator element is measured through the inductance tester and an axial coincidence position is obtained according to the variation on inductance values of the stator element. By contacting a rotor element with coils of the stator element, a contact force is measured by the torque sensorand sent to an industrial personal computer for calculating a coaxial position. By the method, coincidence of the stator element to the rotor element in the axial position and coaxial alignment of theradial position of the stator element are achieved.

Description

technical field [0001] The invention relates to the technical field of precision testing of aerospace instruments, in particular to a method for aligning a radial magnetic levitation stator element of a gyro accelerometer. Background technique [0002] The magnetic levitation bearing of the gyro accelerometer is composed of a rotor and a stator. The stator coil is energized to generate force on the rotor to achieve magnetic levitation. The inductance characteristics of the magnetic levitation element are related to the centering accuracy of the gyro accelerometer, and directly affect the accuracy and stability of the gyro accelerometer. , it is required to measure the inductance characteristics between the stator and the rotor to judge whether the stator components are qualified. [0003] The measurement of the inductance characteristics between the stator and the rotor has high requirements on the relative position of the stator and rotor components. The stator and the roto...
