| Abstract: | In the research of phase information of rotary mechanism,comparatively phase is extracted from multiple frequency phase as diagnosing feature.The fault information included in comparatively phase and its different feature in different faults are also discussed in this paper.It is proved that comparatively phase can get good effect in differentiating fault classes of rotary mechanism. |
