| Abstract: | Based on a study of the phase information gathered from rotary machineries, a fault diagnosis method was proposed in which the time phase signal extracted from the multiple frequency phase was used as the characteristic signal for the diagnosis. The features of the fault information included in the relative time phase were discussed, and the appearance of the information from various faults described. It was shown that the relative time phase was very useful in diagnosing faults of rotary machineries. |

| Keywords: | rotary machinery fault diagnosis relative time phase multiple frequency phase extraction of characteristic value. |
