舰船壳体模块感应磁场的等效计算
The Equivalent Calculation for the Induced Magnetic Fields of a Ship Hull Module
摘要
Abstract
The typical ship hull is a complex construction mainly consisted of thin steel plates and ribs. When the magnetic moment method is adopted to calculate the induced field of the ship hull,a problem could arise due to the complicated data preparation and the huge amount of involved elements. Based on the principle that the product of the area of the cross section and the magnetic susceptibility is constant, the ship hull module can be simplified as a magnetic anisotropic thin plate. To obtain a representative nu-merical example,the magnetic moment method is adopted before and after the simplification of ship hull module,respectively,and the calculation errors are shown to be within 1.5%. Such magnetic equivalent technique not only simplifies the data preparation, but also reduces the element number,which can be very helpful when using the integral calculus method. Overall,it is applicable for the calculation of the in-duced magnetic field of the ship hull.关键词
