| 摘 要： | The parts ofgun often create crack when used for aperiod, in order to avoid accident caused by crack, wem ustdetect it periodically, this is very im portant for thesafely operation and the safety of the operator. Them agnetic flux leakage (M FL) detecting m ethod is verysensitive to the crack on ferrom agnetic m aterials, andwith low cost and sim ple arts and crafts. So it is verywidely used in the crack detection for gun.The principle of M FL non-destruction is as follow s.The gun ' s part… |

| Abstract: | The paper describes the magnetic Dipole model of magnetic flux leakage(MFL) based on the principle of MFL testing, proposes the effects of surface defect width and depth on MFL field, and presents the peak-peak amplitude algorithm that the features of defect signal are extracted. The peak-peak amplitude and separation, signal gradient variation are used as the distinguish criterions of defects. The principle of instrumental hardware design is also introduced. The introduced gun MFL testing instrument is successfully employed in the nondestructive evaluation of gun. |
