英文摘要：

At present, the permanent magnet excitation mode was used in the damage detection of the wire rope, ann me per- manent magnet demagnetization and the instability of the magnetic field were the main problems. In order to solve these prob lems, the overall design scheme of wire rope damage detection system was proposed, the possible damage forms of mine wire rope during application were introduced, the fundamental of magnetic flux leakage testing was elaborated, damage detecting excitation device of mine wire rope based on circumferential magnetization of multiple coils was designed, and excitation effects of excitation device were analyzed by using Ansoft Maxwell software modeling and simulation.
