摘要
为提高航空磁探中潜艇磁场模型精度,分析现有潜艇磁场建模方法,对边界积分法、有限元法、积分方程法、磁体模拟法等主要潜艇磁场建模方法的基本原理和推导过程进行分析。通过数值分析比较各方法的建模精度,最后归纳潜艇低空磁场建模方法的基本要点。
To improve the accuracy of models of submarine magnetic fields in the aero magnetic detection, the existed mod- eling methods of submarine magnetic field was analyzed. Fundamental principles and derived process of main modeling methods of submarine magnetic field was derived, including boundary integral method, finite element method, integral equation method, magnet simulation method. Using numerical analysis, the accuracy of the existed modeling methods was calculated. Finally the basic points of modeling method of submarine magnetic field at low altitude were illustrated.
