本文叙述了爆炸起爆波形对ＥＦＰ形状和速度的影响，对嵌入不同直径隔板（ＷＳ）的战斗部进行了流体编码模拟和试验，试验战斗部采用Ｂ炸药装药，药形罩前设制０～２５ｍｍ不同直径的聚氯乙烯隔板。显示弹丸形状和速度的闪光Ｘ射线照片与流体编码模拟结果进行了比较，并用惠更斯阴影平面高能炸药燃烧法和β燃烧法编制点火程序，对按惰性波形传播的爆炸起爆波进行了模拟。流体编码计算结果与Ｘ射线照片和从试验回收到的ＥＰＰ做了比较，表明ＥＦＰ的长度、直径、质量以及速度的变化都与隔板直径有关．
In this paper, the influence of explosion initiation waveform on the shape and speed of EFP is described. The fluid coding simulation and test are carried out on the warhead embedded in WS with different diameters. ~ 25mm different diameter polyvinyl chloride separator. The flash X-ray images showing the shape and velocity of the projectile were compared with the simulation results of the fluid code. The ignition procedure was programmed by using the Huygens shadow plane high-explosive combustion method and the β-combustion method to simulate the explosive initiation wave propagating by the inertial waveform. Comparisons of fluid code calculations to X-ray photographs and EPP recovered from tests indicate that the EFP length, diameter, mass, and velocity variations are all related to the separator diameter.
