Description
Ultrasonic testing for the KR60 railway in Korea has been conducted by single element ultrasonic testing. In this study, to overcome the limits of single element ultrasonic testing, phased array ultrasonic transducers for detecting defects on the KR60 rail were designed and analyzed based on the inspection results obtained by CIVA software simulation. It was difficult to detect various defects using commercial phased array ultrasonic transducers because of geometric features of KR60 railroad. Therefore, according to the geometric characteristics of the KR60 railroad, the specifications of phased array ultrasonic transducers for the KR60 rail were determined such as nominal frequency, bandwidth, focusing length, width, height, length of piezo-electric material, etc. The acoustic field of the phased array ultrasonic transducers and their S-scan images of artificial defects on the KR60 rail were compared and analyzed
