Abstract :
Metal magnetic memory (MMM) is a new non-destructive testing (NDT) technique. It is important on early diagnostics of fatigue damages and evaluatuion of life time. In order to check the early injury problems and hidden troubles of the steel-cord belts reliably and sensitively, a new type of system based on metal magnetic memory technology is developed. The designs of sensor, detection system and software are given. The floating-point DSP chip is used as the microprocessor in the detection system. The new system which is used for steel-cord belts testing has the characteristics of high sensitivity, small lift-off effect and high reliability.
