爆炸抛撒方式对FAE近场抛撒影响的数值模拟研究

Numerical Simulation on Effect of Explosive Dispersal Methods of FAE Fuel on Near-field Spilling

建立单点中心抛撒二次起爆型云爆战斗部,以及多点径向辅助抛撒二次起爆型云爆战斗部数值计算模型,应用LS-DYNA软件对这2种抛撒方式的二次起爆型云爆战斗部进行云爆剂近场抛撒数值模拟,得到了不同位置观测点的最大压力值和最大速度值,以及在100μs内速度随时间变化曲线。

It built numerical model concerning a single point of center based spill secondary deto-nating explosive FAE warhead and multi point radial auxiliary spill secondary detonating explosive FAE warhead .The two of this dispersion forms of the FAE were simulated the near field spill process of liquid fuel numerically by LS DYNA code ,it gained the maximum pressure and the maximum velocity and the velocity curve of the different loca-tions of observation points in 100 μs ,and the re-sults w ere analyzed .
