Abstract

An electromagnetic acoustic transducer (EMAT) can emit and receive ultrasonic waves though electromagnetic coupling. The non-contact characteristic of EMAT makes no coupling medium, so it is specially concerned by researchers on nondestructive testing and evaluation. This paper mainly introduce the design of electrical parameters and geometric parameters of electromagnetic acoustic surface wave detection system, which is special for the moving-wheels flaw detection, and the principle of moving-wheels flaw detection, it can be used as the key part of the automatic flaw detection system of the moving-wheels.
