A high-precision mechanical gyroscope servo comprehensive test system and method, capable of completing gyroscope servo test and force feedback test, the servo comprehensive test system includes the following parts: gyroscope tooling and related circuits, servo turntable, gyroscope test cabinet, turntable control cabinet , general control cabinet, testing and monitoring data calculation and analysis software. When the gyroscope is used for servo testing, the gyroscope is stable relative to the inertial space. The main shaft is equipped with a high-precision angle measuring device, and the gyro drift can be obtained by making a difference between the main shaft angle of the turntable and the time reference, so as to complete the servo related test. When the gyro is performing the force feedback test, the turntable control cabinet converts the turntable from the servo mode to the position mode, and the gyro test cabinet switches the gyro to the force feedback test state. During the gyro test, the general control cabinet completes the collection, processing, display and storage of the corresponding test and monitoring quantities, and the calculation and analysis are performed by the test and monitoring data calculation and analysis software.
Description
technical field [0001] The invention relates to a high-precision mechanical gyroscope servo comprehensive test system and method, in particular to a single-degree-of-freedom mechanical gyroscope test system, which can be used for testing and calibration of single-degree-of-freedom electromechanical liquid floating and triple-floating gyroscopes. The servo comprehensive test system has two test functions of servo and force feedback, and belongs to the field of gyroscope testing. Background technique [0002] The development of domestic single-degree-of-freedom electromechanical gyroscopes has experienced hydrostatic air flotation, hydrostatic liquid flotation, liquid flotation, and triple flotation. With the improvement of gyro precision, the requirements for the function and accuracy of gyro test systems have also increased accordingly. The servo turntable test is one of the high-precision single-degree-of-freedom electromechanical gyro test methods, which has the advantages...
