Non-Destructive Inspection of Railway Bogie Using Thermographic Method

초록

The inspection of railway bogie has been performed by ultrasonic and magnetic particle testing every three years of general inspection. The magnetic particle method has been utilized in the defect inspection of the bogie frame but the detection accuracy is not high and pretreatment is required before inspection. It is necessary to develop a new non-destructive inspection method to reduce the inspection time and without pretreatment. In present paper, a new thermographic inspection method has been applied. The results show that and the method can be reduced the inspection time of the bogie frame and improved the accuracy of defect detection.
