| Abstract: | Metal Magnetic Memory Technology(MMMT) can be used to find out the stress concentration zone and provide early diagnosis for ferromagnetic structure.The MMMT was applied to test the components on railway vehicles in this paper,and magnetic particle testing was used for re-examination.The results showed the flaws such as crack on the surface of railway vehicles can be found by MMMT.It can predict the dangerous zone on the holes of railway wheels. |
