The singal transient feature detection represent method, and a transient energy evaluation method are used based on the reassigned scalogram for the vibration non-stationary feature representation. The proposed methods are also utilized in the representation of the cone bearing vibration signal feature. Results show that the reassigned scalogram has the signal feature in the time-scale plane with the high resolution, the transient energy evaluation has the transient feature in a more distinct aspect, and thus using for the mechanical fault diagnosis.
