周期胞结构复合装甲抗聚能射流侵彻机理研究

Cycle cell structure composite armour is a new kind of armour with nice protection effect which will be widely used on the armoured vehicles. The cycle cell structure composite armour has excellent performance to disturb the shaped charge jet stability and absorb shock waves. Cycle cell structure composite armour configuration comprised the following layers: high strength steel as the cover plate and metal confined space with liquid polymers as the “sandwich” layer. This project research the mechanism research of cycle cell structure composite armor against the shaped charge jet based on the theory of shaped charge jet stability, the theory of shock wave propagation in inelastic saturated porous media and the theory of impact dynamics and etc. The action process of the cycle cell structure composite armour with the shaped charge jet will described clearly in the theory model.That will be researched in the project the dynamic response characteristics of the liquid polymers, the shock wave propagation characteristics, the effect of the.cycle cell structural parameters for the composite to disturb the stability of the shaped charge jet and the performance of fragmented and scattered the shaped chargejet after the jet penetrated the cycle cell structure composite armour.The mechanism research of cycle cell structure composite armour against the shaped charge jet is a important research content in the research of shaped charge jet with the the targets. This study can prove a theory support for the new kind of .shaped charge warhead and the armor design.
