| Abstract: | It is a stringent task to conduct research of the hydrauhc generator set on the evaluation oI tHe long-term steadiness performance of machines. In this paper, the evaluation of the long-term performance of the hydraulic generator set was discussed, the long-term steadiness was studiced emphatically. The long term steadiness was analyzed by combined time domain, frequency domain and time-frequency domain. The index established in this paper was applied in the condition monitoring and fault diagnosis system of factual hydraulic generator set. It was proved that these productions are effective to the evaluation of machine sets steadiness. |
