Abstract
The research on ship eddy current magnetic field measurement is mostly based on magnetic simulation method. In view of the current used in degaussing station low magnetic compensation degaussing coil cannot meet the requirements of the homogeneous degree of the eddy current magnetic field measurement, this paper USES the particle swarm optimization algorithm, with magnetic modeling of coil system uniformity of evenness as objective function, by means of iteration, the parameters and the number of turns to the position of the coil system parameter optimization calculation, and find the optimal solution. According to the optimal solution, combined with the characteristics of the experimental site and the actual construction of the coil system, the uniformity of the magnetic field generated by the coil system was simulated, and a relatively uniform magnetic field space with the uniformity of more than 95% in the central region was established.
