A method for evaluating the countermeasure capability of ships and magnetic mines

Abstract

The invention relates to a method for assessing counterforce, in particular to a method for assessing the capacity of a ship countering a magnetic mine. The method for assessing the capacity of the ship countering the magnetic mine comprises the steps that through analysis of the actual measurement condition and analog of a computer, an optimal subdivision scheme of a boundary face is searched for through an intelligent optimization algorithm, so that under the poor measurement condition, accurate continuation of a flat magnetic field of the ship is achieved, and depth calculation is conducted through a boundary integral method, so that depth distribution of the magnetic field below the ship is obtained; through comprehensive analysis of a mine magnetic detonator working system, magnetic detonator movement parameters and a countering assessment index and through the computer analog technology, a ship and magnetic mine countering simulation model is established, the magnetic protective capability of the ship is comprehensively assessed, and a credible assessment conclusion is obtained. The method for assessing the capacity of the ship countering the magnetic mine has the advantages that the continuation accuracy of the flat magnetic field of the ship can be effectively improved under the poor measurement condition; through establishment of the assessment indexes of the mine touch width and a mine touch zone, the capacity of the ship countering the magnetic mine can be visually and effectively assessed.

Description

technical field [0001] The invention relates to an evaluation method of countermeasure capability, in particular to an evaluation method of ship and magnetic mine countermeasure capability. Background technique [0002] Due to the high concealment, threat and destructiveness of magnetic mines, as an important means of countering magnetic mine weapons-ship degaussing technology has always been valued by the navies of various countries. At the same time, the research on the anti-magnetic mine countermeasures between ships and magnetic mines is also highly concerned at home and abroad for evaluating the degaussing technology level of ships and predicting the magnetic protection capabilities of ships. [0003] However, relevant research at home and abroad mainly focuses on moving magnetic fuze mines. At this time, the ability of the ship's magnetic field to counter mines depends on the rate of change of the ship's magnetic field curve (ie, the gradient of the magnetic field) at ...

AI Technical Summary

Problems solved by technology

On the one hand, traditional conversion models such as the magnet simulation method often have high data requirements and low precision in the application of real ship magnetic field calculations, which are limited in real ship applications; on the other hand, when the boundary integral method is applied to the magnetic field depth calculation, The measured value of the magnetic field in the plane is difficult to meet in the actual measurement. Although the method of extending the magnetic field in the plane can be used to extend the magnetic field with a limited measurement range to obtain a large plane magnetic field, it often has high requirements for the measurement conditions of the "limited measurement range". It is difficult to realize in practice, and the related continuation calculation method needs to be properly improved before it can be applied in real ships

[0005] In short, with the development of mine magnetic fuze and ship degaussing technology, research on ships and magnetic mine countermeasures can no longer meet the needs of modern ship magnetic protection capability assessment
