Embodiment Construction

[0060] The present invention will be further elaborated below according to specific embodiments.

[0061] Such as figure 1 Shown, a kind of acquisition method of active fragment warhead damage force field, comprises following three parts:

[0062] (1) Research on the damage ability of a single active fragment:

[0063] Let the minimum killing kinetic energy of active fragments be E min , judge whether the target is flammable / explosive, and determine the minimum killing kinetic energy of a single active fragment acting on different types of targets according to the judgment result; when the energy of the active fragment is greater than or equal to the minimum killing kinetic energy, it can cause damage to the target.

[0064] In the process of acting on the target, the active fragments realize the joint damage to the target through the joint action of kinetic energy collision and chemical energy release. For explosive targets, regardless of the impact of deflagration chemica...

Abstract

The invention discloses a method for acquiring an active fragment warhead damage power field, and provides a method for researching the active fragment warhead damage power field by establishing related theories on the basis of an inert fragment warhead damage power field and combining damage performance analysis of a single active fragment collision target plate. According to the method, the influence of warhead structure parameters and terminal ballistic trajectories on the damage power field can be analyzed, and guidance and reference are provided for warhead design and terminal ballistic trajectory optimization.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency damage and application of active materials, and in particular relates to a method for obtaining a damage force field of an active fragment warhead. Background technique [0002] Active fragments can generally be prepared by mixing, molding and sintering hardening of fluoropolymer matrix and metal particles. Under the action of strong dynamic load in the process of collision and penetration into the target, the active fragments will be activated to undergo chemical reactions, especially After penetrating the target's protective layer, it can achieve efficient damage to the target behind the target. [0003] It is precisely because of the unique thermal-mechanical coupling response of active fragments that its research in the field of high-efficiency damage has become more and more extensive, and it has been vigorously studied by countries all over the world, especially in the preparation of...
