  • A FUZZY EVALUATION AND PREDICTION METHOD FOR RUNNING STATUS OF MECHANICAL EQUIPMENT WITH OCCURRENCE PROBABILITY OF FAILURE MODES
    Publication number: 20190005400
    Abstract: The present invention discloses mechanical equipment running state fuzzy evaluation and prediction methods with occurrence probability of failure modes. The evaluation method includes the following steps: S1, determining a product set and a failure mode set thereof: S2, determining a feature set corresponding to each failure mode; S3, calculating the degradation degree of each feature; S4, calculating the occurrence probability of each failure mode; S5, calculating the membership degree of the occurrence probability of each failure mode; S6, fuzzy comprehensive evaluation is applied to the running state of the part; and S7, fuzzy comprehensive evaluation is applied to the running state of mechanical equipment. The invention further discloses a mechanical equipment running state prediction method.
