Abstract

This application relates to the dry friction test of the liquid floating gyroscope, in particular to a method for automatic zeroing of the position of the liquid floating gyroscope float: collect the fluctuation signal of the liquid floating gyroscope float, and obtain the position value queue of the liquid floating gyroscope float; according to the position value Queue, calculate the control current value of the torque device; control the output torque of the torque device according to the control current value, so that the float of the liquid floating gyro returns to zero. The torquer can accurately control the fluctuation of the liquid floating gyro float, so that the zeroing effect of the liquid floating gyro float under the action of the torquer can maintain good consistency and accuracy, shorten the zeroing time; avoid the possibility of external vibration during manual testing The damage to the float jewel bearing helps to improve the reliability and service life of the liquid floating gyroscope. The application also discloses a device for automatic zero adjustment of the float position of the liquid floating gyro.

Description

technical field [0001] The present application relates to dry friction testing of liquid floating gyroscopes, and in particular to a method and device for automatic zero adjustment of the float position of liquid floating gyroscopes. Background technique [0002] In recent years, with the vigorous development of inertial navigation systems, new technologies such as fiber optic gyroscopes, laser gyroscopes, electrostatic gyroscopes, vibrating gyroscopes and miniature solid-state inertial devices have been maturely applied, but traditional liquid floating gyroscopes still have an absolute advantage in accuracy. At present, the inertial navigation system with high precision, high reliability and long life still uses liquid floating gyro. [0003] The dry friction test of the gyroscope is to test the friction when the gyroscope is not filled with floating liquid. The test principle is the same as the wet adjustment of the gyroscope. It is to apply positive and negative torque cu...
