反潜战斗部对耐压壳结构的毁伤威力评估方法与实验

Considering the characteristics of different anti-submarine (torpedo / depth charge) warheads, including multiple effects of underwater explosions, and multiple styles of target structures, the normalized comprehensive damage power characterization and assessment of warheads were studied. Based on the damage of the most representative hull structure (pressure hull) and comprehensively considering the effects of large deformation, tearing, and perforation, a method to quantitatively characterize and evaluate the power of the warhead through a comprehensive damage power index was proposed. A test target simulating the damaging effect of single-hull, and the double-hull was designed, and three model warheads were tested. The comprehensive power of the three warheads against the two types of structures was obtained. The results showed that: the proposed comprehensive power assessment method has scientific rationality and engineering practicability; it can quantitatively compare and analyze the differences in the damage power of the same warhead to different hull structures and the damage power of different warheads to the same hull structure; under the same conditions, the blast warhead and the shaped charge warhead had relatively greater damage to the single-hull target and double-hulled targets; implosion warheads had better damage power to both types of targets; for different targets, the damage power of the blast warhead, the implosion warhead, and the implosion warhead dropped by more than 90%, nearly 80%, and less than 20%, respectively.
