摘要

In order to discuss the propagation characteristic of shaft-rated(SR) electromagnetic(EM) field produced by the ship of multiple propellers in shallow ocean, analytical expressions of EM was derived by several time-harmonic vertical dipoles model based on single time-harmonic vertical dipole method. Firstly, the paper built the physical model of single time-harmonic vertical dipole in triple-layer mediums with uniform speed movement. Then from two factors of phase and frequency, according to vector superposition principle, the EM expressions were solved by n time-harmonic vertical dipoles in fixed position so as to provide theoreticl law for the research of propagation characteristic. Some valuable conclusions were rearched through simulation, including finding the maxmum EM value when frequency was same and phase was zero, and frepuency variation was no-effect to the SR EM field when phase was same. Lastly, the exprement results were anatomotic with theoreticl analysis and demonstrated the effectiveness the expressions.
