Efficient Methodology for Optimizing Degaussing Coil Currents in Ships Utilizing Magnetomotive Force Sensitivity Information

摘要

This paper presents an efficient methodology for optimizing degaussing coil currents in ships to minimize magnetic field anomaly underwater. For fast search for an optimum, a magnetomotive force sensitivity formula is adopted. Especially the method does not require any numerical field analyses to assess an objective function during optimization process providing experimental field data on each coil effect are given. The validity of the proposed method is tested with a model ship.
