Abstract

Work underway at the NBS in developing an automated on-line EMAT system for on-site railroad wheel inspection and flaw detection is described. The transmitter and receiver transducers are designed for pitch-catch operation and operate on Rayleigh waves. The system includes a function generator, gated power amplifier, line driver, and impedance matching circuits. Beam optics and operating characteristics are discussed. Signal amplitudes as a function of transducer position around the wheel circumference and other results are plotted. Preliminary results indicate that the electronics and transducer design generate a strong Rayleigh wave in a cast iron wheel.
