Wheel is one of the most important parts on the train. Some harmful cracks may appear in wheel rim during operating and threaten train safety. In order to eliminate such kind of risk, wheel should be checked by ultrasonic and other technique regularly. This paper introduces a wheel crack wayside inspection method by applying arrayed conventional ultrasonic probes. With the specially designed track structure, ultrasonic probes are arrayed between the support and guard rail for wheel crack inspection. The test results show that Φ3mm side drill hole in wheel rim can be well detected at the train passing speed of 5~40km/h. At present, more than 100 sets of such system are applied on site in China.
