The Study On New Type Of Multimode Warhead

As the multimode warhead,it can be the corresponding damage by different target in order to different battlefield target.Now,the research of shaped charge damages are JET,Explosively Formed Penetrator(EFP)and Jetting Penetrator Charge(JPC).This paper through the research and analysis of charge and multimode warhead,analysis of detonation mod and drug horn type cover structure parameters on the damage influence law of forming,to search on a single charge structure formed under the best match between jet and lever type jetting parameters,and based on the Jet formation theory and the theory of detonation by the numerical simulation software LS-DYNA.Based on the traditional structural design of liners,combining design features for dual mode warhead shaped influence parameter of deep research,and on the thickness of the metal shield to do a separate analysis and research,and use trumpet-shaped metal shroud to get rod penetrator.Then other parameters of the horn cover,main parameters were the height of horn(H),the arc radius of horn(R),and the thickness(h).Under the condition of height arm was 0.9D,the arc radius of horn was 1.25 D,the height was0.5D,and the thickness was 0.05 D,the JPC was formed by single point detonation and the JET was formed by annular detonation.Finally,grey correlation analysis method is introduced to penetrator influence factors analysis of the correlation.To get the parameters of the influence of size: H>R>h.
