Abstract

Abstract

Three layered defense models were designed based on the multiplayer defense structure of a warship. Contact explosion experiments with three different masses of explosive were carried out three times in the centers of the outside plates. The defense effects of multiplayer structures were explored by analyzing the dimension and shape of crevasses. Experimental results show： (1) the vacant cabin of the multiplayer defense structure has great importance to expand and decompress the effect of detonation products and shock wave; (2) liquid cabin can alleviate the damage of fragments, detonation products and shock wave. The multiplayer defense structure has great importance to diminish the damage of contact explosion.
