摘要：
In order to improve the damage of the shaped charge to the ship target, a new charge structure was designed according to the theory of stress wave basis and impact dynamics. The forming process of jet was simulated by using AUTODYN-2D, and the influence of auxiliary liner material on the forming and performance of jet was analyzed. The simulated results show that the new charge structure can form a high-speed jet with less slugs and a narrow tapered head, and the jet speed is positively correlated with the impact resistance of auxiliary sphere liner material, and is negatively correlated with the impact resistance of auxiliary conical liner material. The energy utilization rate of liner is negatively correlated with the impact resistance of auxiliary liner material. When the auxiliary liner is made of tungsten and the auxiliary conical liner is made of copper, the jet shaping of truncated liner is better than the others, the jet speed reaches 13 460 m/s, the energy utilization rate is 15.419%, the effective jet length is 68.26%, and the effective jet mass is 66.02%. © 2018, Editorial Board of Acta Armamentarii.
