Method for detecting, analyzing and screening vibration signals of motor of static-pressure liquid-floated gyro-accelerometer

The invention relates to a method for detecting, analyzing and screening vibration signals of a motor of a static-pressure liquid-floated gyro-accelerometer, and belongs to the technical field of static-pressure liquid-floated gyro-accelerometers. The method includes acquiring vibration acceleration signals generated when the gyro-motor mounted on a support component runs, and performing time-frequency analysis on the vibration acceleration signals; tracking an integral gyro-accelerometer adjustment procedure; counting test data of an integral table; comparing the vibration acceleration signals of the gyro-motor to the test data of the integral table; summarizing time-frequency characteristics of the vibration acceleration signals of the gyro-motor; providing motor vibration characteristic indexes which are quantitatively measured in a floater component assembly procedure. The vibration acceleration signals of the gyro-motor correspond to the gyro-accelerometer with high stability precision in the integral table K1. The method has the advantage that a guidance effect can be realized in follow-up accelerometer manufacturing procedures.
