Method of and apparatus for detecting defects |
| abstract |
A method of and apparatus for detecting defects in a railway rail including a search unit and preferably a roller search unit ("RSU'') mounted on a test vehicle and in rolling contact with the running surface of the rails to inspect each rail. The RSU includes a tire filled with a liquid and a transducer assembly mounted within the tire. The transducer assembly includes one or more arrays of ultrasonic transducers directed toward the running surface of the rail. The liquid provides a coupling between the transducers through the tire wall and into the rail. Beams transmitted by the one or more arrays of ultrasonic transducers may be dynamically adjusted to compensate for the varying profile of the rail head and running surface. |
