深海中潜艇腐蚀相关磁场全空间分布特征分析
Research on the corrosion-related magnetic field produced by a submarine in deep seas
摘要
Abstract
In order to study the distribution characteristics of the corrosion-related magnetic field produced by a sub-marine in deep sea, a static horizontal electric dipole is adopted to simulate the field source and an air-seawater two-layer model is adopted to simulate the deep sea environment. Based on the solution of the electric scalar poten-tial of the static electric dipole obtained by using the mirror image method, the distribution of the static magnetic field produced by the corrosion or anti-corrosion current was obtained and proved to satisfy the field equations and the boundary conditions under the constraint relation between the electric scalar potential and the magnetic vector potential . Then the space distribution features of the magnetic field were analyzed by using the numerical calculation method. The research results show that, because the corrosion-related magnetic field of a submarine in deep seas has measureable magnitude and obvious distribution characteristic in all space, it will become an important signal source for detection or striking. In particular the components of the corrosion-related magnetic field degenerate with the inverse square of the distance,and the attenuation is slower than the magnetic field of the ferromagnetic materi-als, so it will help for remote detection. The research results lay a foundation for further applications.关键词
