摘要
铁磁设备的磁性是低磁舰艇磁性的主要来源,在用静磁场积分方程法求解低磁舰艇的磁场时,由于铁磁设备众多导致的磁源复杂性严重影响了计算的速度,为此提出了设备磁场简化建模方法。为验证该方法的正确性和有效性,将其应用于地磁场磁化下柴油机的磁场计算中。计算值和实际值的一致性表明该方法完全可应用于低磁舰艇设备的简化建模,有一定的工程实用价值。
The magnetism of ferromagnetic devices becomes the main original magnetism of the low magnetic ship.The numerous ferromagnetic devices make the magnetic origin very complex and this affects the computing velocity seriously.So a simplified modeling method for ferromagnetic devices is presented in this paper.Anexample of a diesel engine in geomagnetic field is given to verify the method's efficiency and accuracy.The result of the example is satisfying and the proposed method could be applied in the practical engineering.
