摘要/Abstract

摘要： 提出一种六自由度电磁探测的快速数值算法,对500 mm×500 mm×500 mm范围内的空间磁场进行数值仿真,并与电流环近似算法和严格算法进行比较,归一化计算时间比为10⁶:70:1,结果表明该算法可行可靠.最后讨论怎样有效地克服螺线管线圈的有限长效应引起的偏差,从而进一步提高探测系统的探测精度及稳定性.

Abstract: A fast numerical algorithm for six degrees of freedom electromagnetic probing is proposed, to simulate magnetic field inside a space of 500 mm×500 mm×500 mm. Compared with strict algorithm and current-loop approximation algorithm, normalization computing time ratio is 10⁶:70:1. It shows that the algorithm is feasible and reliable. Finally, how to effectively minimize deviation caused by limited length effect of solenoid coil is discussed to further improve the probing precision and stability of the probing system.
