摘要

Pulsed eddy current (PEC) technique generates responses over a wide range of frequencies, containing more spectral coverage than traditional eddy current inspection.Eddy current pulsed thermography (ECPT), a newly developed non-destructive testing (NDT) technique, has advantages such as rapid inspection of a large area within a short time, high spatial resolution, high sensitivity and stand-off measurement distance.This paper investigates ECPT for the evaluation of gear fatigue tests.The paper proposes a statistical method based on single channet blind source separation to extract details ot gear fatigue.The discussion of transient thermal distribution and patterns of fatigue contact surfaces as well as the non-contact surfaces have been reported.In addition, the measurement for gears with different cycles of fatigue tests by ECPTand the comparison results between ECPT with magnetic Barkhausen noise (MBN) have been evaluated.The comparison shows the competitive capability of ECPT in fatigue evaluation.An open access database of ECPT for gear fatigue evaluation is provided, and freely obtained to further analysis for gear fatigue evaluation.
