摘　　要：为了研究炸高因素对爆炸成型弹丸（EFP）成型性能及侵彻深度的影响,利用有限元软件LSDYNA,建立了球缺罩型聚能装药仿真计算模型。研究了十种不同炸高条件下,EFP着靶时性能参数和侵彻45#钢靶过程,并与该装药静破甲试验结果进行了对比分析。结果表明：试验与数值模拟结果较吻合,最大误差为10%,EFP装药的有利炸高与装药直径之比为3.9～4.4,最大破甲深度约为装药直径的0.92倍。In order to study the relationship between blasting height and the penetration depth,the finite element software LSDYNA was used to simulate the penetration process of the EFP shaped charge,and the EFP performance and penetration ability under different blasting height were also discussed by comparing with experiment results. The results show that the experimental date was similar to the numerical simulation. The EFP showed better performance when the ratio of effective blasting height versus diameter of shell-bottom was about 3. 9 ~ 4. 4,and the ratio of maximum penetration depth versus the charging diameter was 0. 92.
