摘要 通过合理设计隔板的几何尺寸和炸药的装药量,对在药型罩凸面粘附隔板的方法形成尾翼型爆炸成型弹丸(EFP)进行试验研究。同时利用LS-DYAN对新方法形成的尾翼进行数值模拟,通过数值计算得到了药型罩微元上的压跨速度和压力曲线,从药型罩微元压跨速度变化和药型罩表面爆轰压力变化的角度出发,分析了新方法形成尾翼的可行性。试验与数值模拟结果表明,贴隔板法可以形成尾翼型EFP。 Explosively formed projectiles with fins formed by attaching cover on the shaped liner was studied via reasonable design figure of cover and capacity of detonator. At the same time, the numerical simulation was implemented on this new way by LS-DYNA. The velocity vs. pressure curves on the liner cell are obtained. The feasibility is discussed on how to form fins from variety of velocity and pressure on liners which results from the numerical simulation. The results of experiment and numerical simulation by LS DYNA show that EFP with fins can be obtained by this new way.
