Study of magnetic flux leakage detecting simulation of sucker rod based on Maxwell 2D |
| |
Abstract: | The magnetic flux leakage detection method is always used in the nondestructive testing of sucker rod. The method of establishing magnetic flux leakage detecting simulation model of sucker, the designing method of magnetic exciting coil size and the simulation course of defect detection are discussed briefly in the simulation software Maxwell 2D. Based on the traditional detecting method, the magnetic flux is optimized in the design. And the magnetization effect of sucker rod and the defect detection result before and after the optimization are compared by simulation. The results show that the optimized magnetization structure can effectively shorten the distance of end effect, also can improve the sensitivity of defect detection. |
