A modeling method for ship corrosion electric field based on DC point current source array model. Its characteristics are: select the DC point current source as the basic calculation unit to construct the data equation of the ship corrosion electric field model, part of the DC point current source is arranged at the position of the propeller and the auxiliary anode, and the other part is arranged at the underwater part of the ship at even intervals Both sides of the centerline. The effect and benefit of the present invention are that, compared with the electric dipole, the DC point current source can physically reflect the characteristics of the ship corrosion electric field source, can improve the stability of the ship corrosion electric field model, and can ensure the depth of the ship corrosion electric field , The accuracy of distance conversion.
Description
Modeling method of ship corrosion electric field based on DC point current source array model Technical field The invention belongs to the technical field of ship underwater electric field measurement, relate to a kind of ship corrosion electric field modeling method, particularly In particular, it involves a modeling method of ship corrosion electric field using a DC point current source as the basic calculation unit. Background technique Ship corrosion electric field modeling is one of the key links of ship underwater electric field measurement data processing, and its main function is Carry out distance conversion and depth conversion on the original data of the ship's electric field, and convert the data of different water depths and different positive and transverse distances to the water The same evaluation line with a certain depth and positive transverse distance can ensure the objectivity and accuracy of the ship's electric field evaluation. The current ship is...
