Technique of electromagnetic ultrasonic surface wave for wheel flaw detection

In China,the relevant department of railway mainly takes examining and repairing the train wheels regularly,namely examining and repairing the wheels in a planned way with a large amount of manpower gathered during the fixed time.This way needs great manpower and material resources.In order to improve it,we have developed the automatic flaw detection system of the moving-wheels.This paper mainly introduced the emitting receiving system of the electromagnetic ultrasonic surface wave and utilized the principle that the electromagnetic ultrasonic surface wave can detect flaws of the moving-wheels to analyze the ways of dealing with some important detection data and fault waves.
