Abstract

The application relates to a dry friction test of a liquid-floated gyroscope floater, in particular to a method for position automatic zero-setting of liquid-floated gyroscope floater. The method comprises the following steps of acquiring a fluctuation signal of the liquid-floated gyroscope floater to obtain a position numerical value queue of the liquid-floated gyroscope floater; calculating a control current value of a torquer according to the position numerical value queue; and controlling the output torque of the torquer according to the control current value to return the liquid-floated gyroscope floater to the zero position. The torque can be used for precisely controlling the fluctuation of the liquid-floated gyroscope floater, so that the zero-setting effect of the liquid-floated gyroscope floater under the torque effect can maintain good consistency and accuracy, and the zero-setting time is shortened; the damage on a floater jewel bearing by the external vibration in manual testing can be avoided, and the reliability and the service life of the liquid-floated gyroscope can be improved. The application further discloses a device for position automatic zero-setting of the liquid-floated gyroscope floater.

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...
