Paper Abstract

Ultrasonic image formed by Phased Array Ultrasonic probes placed on wheel tread is deformed. Especially for ultrasonic image around area of wheel disk hole, because that area has a complex construction and a long ultrasonic path. According to probes layout and beam angle, correction algorithms are designed to revise deformed ultrasonic images. Tests on CRH reference wheels with manmade defects and tests on CRH wheels on train shows that the correction algorithms proposed can correct all types of CRH wheel's ultrasonic images, and the calibration can meet the requirement of field application.
