摘要：An apparatus for detecting defects in a railway rail includes a search unit andpreferably a roller search unit (“RSU”) mounted on a test vehicle and in rolling contactwith 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 assemblyincludes one or more arrays of ultrasonic transducers directed toward the runningsurface of the rail. A laser profiler mounted on the test vehicle in combination with alinear encoder provide profile data which is communicated to a system controller todynamically adjust the focal laws for the one or more arrays of transducers to
dynamically steer the transmitted beams to produce the ideal inspection beam sets whilethe test vehicle is in motion.
