It should be understood that the detailed description is presented by way of example only and is not intended to limit the invention.
FIG. 1 is a schematic diagram of an evaluation flow of the present invention.
Detailed Description
The method comprises the following steps, as shown in the accompanying drawings:
(1) Determining a typical submarine target;
(2) Obtaining a parameter threshold value of the damage effect of the hull structure through experimental study or theoretical calculation;
(3) Establishing an evaluation target plate;
(4) Obtaining damage effect parameters of the warhead on evaluating the action of the target plate through experimental study or theoretical calculation;

The anti-diving warhead is the warhead to be evaluated.
A typical submarine target refers to any targeted reference target selected for evaluation of the warhead's ability to damage.
The damage of the submarine body structure refers to the loss of buoyancy of the submarine body caused by the instability of the shell strength or the water inlet of a crack due to the deformation of the submarine body structure under the load of the anti-diving warhead.
The damage effect parameter is a target plate damage effect parameter result obtained after the warhead load acts on the target plate by using a test method, a theoretical calculation method or a numerical calculation method. The warhead should be installed vertically with the center of the residual target plate and placed under water to a certain depth. The damage effect which can be generated by the boat body structure under the load of the anti-diving warhead is mainly shell deformation, energy accumulation hole breaking or tearing and cracking, and the three damage effects can be respectively used with maximum deformation deflectionEnergy-gathering broken hole diameter->Tear breakLength ofThree parameters of damage effect are used for characterization.
The threshold value of the damage effect parameter of the hull structure refers to the critical value of the damage effect parameter which enables the submarine to reach different degrees of damage grades.
The submarine damage grade refers to the degree of submarine damage caused by the damage of the hull structure, and is divided into three damage grades. The first-level damage refers to disassembly or sinking of the submarine, and is mainly characterized in that the submarine body structure is broken or deformed in a large scale, the strength of the submarine body is unstable or the buoyancy of the submarine body is irreversibly reduced, and finally the submarine body is sunk; the II-level damage means that the submarine must float up immediately and cannot continue to fight, and the submarine mainly appears as a mesoscale crack or deformation of the hull structure, the strength or buoyancy of the submarine hull is seriously reduced, and the submarine must float up immediately and cannot continue to execute the fight task; the III-level damage refers to the decline of the combat capability, which is mainly represented by the small-scale break or deformation of the hull structure, the decrease of the hull strength, or the effective blocking of broken holes after the starting of the damage control, the submarine does not need to float up immediately, but the combat capability is reduced.
For the energy-gathering broken hole diameter, the damage effect parameter thresholds corresponding to 3 damage grades of the submarine are respectively as follows、/>、 />. Namely when energy-gathering broken hole diameter +.>The submarine damage reaches the level I damage; when->The submarine damage reaches the II-level damage; when->The damage of the submarine reaches the III level. Similarly, the maximum deformation deflection damage effect parameter threshold values corresponding to 3 damage grades are respectively +.>、/>、/>The threshold value of the damage effect parameter of the tearing break length is +.>、 />、 />。
The evaluation target plate refers to a circular plate target structure with an air back cabin, which is built according to the hull structure of a typical submarine. The material and structure size of the explosion-facing circular plate and ribs of the target plate are consistent with those of the pressure-resistant shell of the boat body structure, the diameter of the circular plate target surface is determined by not generating shearing damage along the edge, and the height of the air chamber is determined by not striking the bottom when the explosion-facing circular plate split is bent inwards. The side plates and the back plate of the target body are properly reinforced to improve the overall strength of the target, and larger deformation is not required to be generated.
The comprehensive damage effect index of the warhead refers to a dimensionless calculated value obtained by comparing three damage effect parameters with the damage effect parameter thresholds corresponding to the damage levels respectively and then adding the three damage effect parameters.
For level I lesions, the overall lesion effect index is obtained.
。
For class II lesions, the overall lesion effect index is obtained.
。
For class III lesions, the overall lesion effect index is obtained.
。
The comprehensive damage effect index can quantitatively represent the damage capability of the anti-diving warhead to the hull structure. According to the requirements of different submarines on the damage grades, the comprehensive damage effect indexes corresponding to different anti-submarine warheads are obtained, and the larger the index is, the stronger the damage capability of the warheads is.
