Abstract��With the rapid growth of railway transportation in China, there are more and more strict requirements for the quality and testing of railway wheels. Using ultrasonic phased array in the testing of railway wheels, phased array scanning images of railway wheels interior flaws were analyzed. The emulated software was also used to do covering simulation for phased array acoustic beam, applying in wheel products including wheel flange, wheel flange root, tread and wheel rim area within certain depth. In summary, the technology of ultrasonic phased array enriches the methods of ultrasonic intact testing.
