Research Of Liner Parameters On The Effects Of Explosively Formed Projectiles

This thesis for master degree mainly study the explosive type cover parameters of explosively formed penetrator effect, source of the subject in the factory actual development project, in the infantry rocket tandem warhead primary charge structure design based, with the damage effect of homogeneous steel target, and concrete target and target for the purpose of the study. Starting from the principle of cumulative effect,summarizes the formation mechanism of shaped charge, explosively formed penetrator. On the basis of this, the structure of the main level is determined by optimizing the parameters and the design of the main level, which can make the explosive forming of the target.In medicine research cover parameters of explosively formed penetrator impact process, arranged Mohaupt effect principle of structure of drug using, by the change of medicine cover materials, wall thickness, angle and radius of curvature parameter to study medicine in the power of influence. In this paper, we use empirical formula to calculate the charge structure, and carry out the numerical simulation. By analyzing and optimizing the shape and material parameters of the medicine, the efficiency of the optimization is greatly improved.Combined with the factory actual situation, the design of charge structure multi round test, the test, the primary charge of homogeneous steel target, reinforced concrete wall target penetration depth can meet individual rocket tandem warhead with functional requirements. In order to achieve the limited weapon launch platform, the target has a large hole diameter, but also has a certain ability to wear. Maximize product performance. Its technical indicators, in the domestic leading level.
