[0121] Combined with the experiment, the above methods are comprehensively used to identify the degradation state of the planetary gear. The planetary gear failure experiment was carried out on the DDS mechanical failure comprehensive simulation test bench of Spectra Quest Company in the United States. In this experiment, a total of 9 degradation states of normal planetary gears, fractured planetary gears, and 4-stage degradation states of pitted planetary gears were measured. By analyzing the collected vibration signals, the established degradation state identification method was tested.
[0122] The planetary gear fault simulation experiment was carried out on the DDS mechanical fault comprehensive simulation test bench, and a total of 9 degradation states of normal planetary gears, fractured planetary gears, and pitting planetary gears were extracted. According to the preliminary analysis of the basic parameters of the planetary gearbox on the test bench and its early vibra...
