Application of a New Sensor for Diagnostics of Weld Defect in Railway Bogie Frame

초록

The fatigue cracks have been initiated and propagated in weld of railway bogie frame. For the detection of the crack, usually MT and UT are widely used in non-destructive inspection of railway. However, the time and cost for the inspection are required due to preprocessing for NDT. In the present paper, the applicability of the new techniques has investigated the continuous monitoring of weld of railway bogie frame without preprocessing for NDT. The results show that the sensitivity of the continuous monitoring of weldment of railway bogie frame is higher than that of the conventional techniques.
