摘　　要：文中采用LS-DYNA软件,以70mm弧锥结合型爆炸成型弹丸(EFP)侵彻40mm厚45#钢靶数值模拟过程为例,针对弧锥结合型EFP成型、空中飞行和侵彻钢靶过程的特性进行了研究。模拟结果与试验结果相吻合,表明采用的数值模拟方法正确,结果分析合理。为弧锥结合型EFP的研究提供了方法和有价值的特性规律。The software of LS-DYNA was used to analyze 70mm EFP penetrating 40mm thickness 45 # steel target, The forming, flying and penetrating steel target characteristic of the arc-taper EFP was studied. The result of numerical simulation was in accordance with the experiment. It shows the numerical simulation is right and the analysis is reasonable. It provides the way to study are-taper EFP and the valuable rule.
