钢板磁导率变化对船舶感应磁场的影响
Effects of Steel Magnetic Properties on Induced Magnetic Fields of a Ship
摘要
Abstract
The permeability of steel is changed greatly under different heat treatments and technologies, including jointing and incision, and these factors lead to the changes in the magnetic field of the ship. On the basis of electromagnetic theory, the effects of steel magnetic properties on induced magnetic fields are investigated in this paper through simulation,and the range of magnetic field variation is also analyzed. Certain ship model experiments are conducted to further validate the proposed theory. The results reveals that while the permeability of steel is changed by 20%, the trend of curves for the induced magnetic fields stays constant,but the amplitude value of the induced magnetic fields changes significantly,with the longi⁃tudinal magnetic field varying by 19.3%,the athwartships magnetic field varying by 17.1%, and the verti⁃cal magnetic field varying by 16.2%.关键词
