Modeling of ship corrosion related shaft-rate electromagnetic field
摘要
Abstract
To conduct modeling research for the source of shaft-rate electromagnetic field, on the basis of the generation mechanism of the underwater corrosion-related shaft-rate electromagnetic field of a ship and in view of the building principle of a low-frequency transmitting station , this paper proposed a current loop modeling for a ship.This model uses the closed circuit formed by the following parts as an example: sea water, propel-ler, axis of rotation, hull, and auxiliary anode, i.e., the shaft-rate electromagnetic field source is equivalent to a closed curve formed by the curves related to the skin depth with the axle of rotation as a chord .A verifica-tion test was conducted in the lab.Experimental results show that the field source of corrosion-related shaft-rate electromagnetic field includes not only the current line between the auxiliary anode and the propeller but also the spatial current distributed in sea water.The generation mechanism model of the shaft-rate electromagnetic field based on the current loop model is consistent with the experimental results.The model offers a new concept and method for modeling the shaft-rate electromagnetic field and conducting research on the propaga-tion law.关键词
