摘　　要：描述了爆炸成型弹丸(explosive formed projectile,EFP)对有限厚靶板的侵彻过程,建立了计算EFP对有限厚靶板侵彻过程参数的一维分析模型。基于该模型编制了程序代码,对EFP侵彻有限厚靶板的后效参量及极限穿透速度进行了计算,并和试验结果进行了比较。证明该模型能较准确地对EFP侵彻有限厚靶板后效参量进行计算。A one-dimensional model was proposed to describe the process of EFP （explosive formed projectile） penetration into a target of finite thickness. The aftereffect prametors and the limit penetrating velocity were calculated with a program based on the proposed model. Numerical results are in agreement with the experimental results.
