Numerical Simulation on Magnetic Flux Leakage Testing of the Steel Cable at Different Speed Title

摘要：

The safety operation of steel cable is vital and the cable should be maintained through regular inspection. Magnetic flux leakage (MFL) method is a popular inspection technique. For the online nondestructive testing (NDT), the eddy current arises in the steel cable due to the relative movement of the cable and the MFL system, which affects the defect field and causes the difficulty in the defect inspection. In this paper, for axial MFL system with permanent magnet excitation at different speeds, the distribution of eddy currents, magnetic flux lines and magnetic leakage field are investigated by numerical simulation. The results provide a deep insight into the design of the MFL system.
