一种潜艇内外磁场换算算法的实验验证

An experimental verification of conversion of magnetic field inside and outside submarine

将磁矩作为潜艇磁场的虚拟源,通过磁场变化量推导了潜艇内外磁场变化量的关系式,解决了制约闭环消磁技术发展的核心问题。并以封闭的铁质空心圆筒模拟潜艇,测量模型内外磁场变化量,对内外换算关系式进行了实验验证,实验结果表明,用该关系式由内部磁场换算外部磁场,误差可以控制在10%以内。

Using the magnetic moment as the virtual source of the magnetic field of submarine can deduce a relation of conversion of magnetic field variation inside and outside submarine. The kernel limiting the development of the closed loop degaussing was solved. A submarine was simulated with a hollow close iron cylinder for measuring the magnetic field variation inside and outside the model, with which an experimental verification was carried out, with the error in this conversion less then 10%. The result shows that this conversion is very feasible and valuable.
