文中研究了油管局部缺陷和壁厚减薄缺陷的漏磁场检测原理。
Based on the magnetic leakage flux technique, the principle of localized defect inspection and wall thickness measurement in oil well tubing has been researched.
板料厚度大，不易起皱，但壁厚减薄率大，因而成形精度不高。
The thick blank is difficulty wrinkled, but the blank thinning is larger and result in a low forming precision.
最后利用优化结果进行模拟，壁厚减薄率明显下降，得到了满意的效果。
Finally, to simulation the results of optimization, the wall thickness reduction decreased and get satisfactory results.
