Abstract: The flywheel is the actuator of a space satellite, and its performance determines whether the satellite can operate normally. The current flywheel test system has a single function, and the manual efficiency of regular calibration of the test system is low. Focusing on actual demand, a multi-functional generalized automatic test platform is developed. Based on QT, a flywheel test platform is developed, which can take into account multi-model and multi-protocol modular software, and can complete the series/parallel test of the self-defined timing function of the 6-way flywheel control board, and realize the one-click test and the regular automatic calibration function. After experimenting and practically results, the test system solves the problem that a test system can only test one flywheel product in the traditional sense, and improve the test efficiency. In practical applications, it solves the complex operation problem of manual calibration by metrological calibration personnel during regular calibration, and overcomes a series of problems that are prone to errors and low accuracy.
