摘要:
为获得起爆方式对变壁厚药型罩形成毁伤元的影响规律，采用有限元分析软件AUTODYN-2D对变壁厚药型罩装药结构在中心点起爆、环起爆、点环起爆和面起爆4种起爆方式下形成毁伤元的过程进行数值仿真研究。结果表明：采用不同的起爆方式，装药会产生不同的爆轰波形，变壁厚药型罩会分别形成向前压拢型EFP、向后翻转型EFP、准球形EFP和倒锥形EFP。4种不同形态的毁伤元最终速度相差不大，但达到飞行稳定的时间不同，采用中心点起爆形成的向前压拢型EFP所需时间最短。
Abstract:
In order to understand the effect of initiation ways on the damage element forming process produced by variable thickness liner,the numerical simulation of the process under four initiation ways, including point initiation,annular initiation,point-annular initiation and plane initiation, was carried out by using finite element analysis software AUTODYN-2D.Results show that different ways of initiation produce different shapes of detonation wave,and liner can form forward folding EFP, backward folding EFP,quasi-spherical EFP and inverted cone EFP. Velocities of the four different damage elements are similar,but time for EFP flying stability is different,and forward folding EFP needs the least time under point initiation.
