As one of the key components of the railway transportation, the condition of the railway wheelsets are essential, especially in the field of heavy-load and high-speed application. Normally, ultrasonic or magnetic particle testing is executed on the wheelsets detecting when the train is stopped for maintenance or after the wheelsets are disassembled from the train. A method for dynamic wheelsets defect inspection by applying ultrasonic technology is described in this paper. The defects in wheel rim and straight-shaped wheel disk can be detected when the train is passing by with a low speed of 5km/h typically. The inspection tracks are specially designed to make the tape line area of wheel tread be available for inspection. The ultrasonic probes are arrayed between the supporting track and the guiding track. The testing results show that 3 mm side drill hole in wheel rim and wheel disk can be found out at the running speed of 3 - 10km/h. The system has been applied in Wuhan depot, China, which is used for Harmony Locomotive wheelsets defect inspection and about 200 wheelsets are inspected each day.
