摘要
用 L S- DYNA程序对小长径比聚能装药逆向环形起爆时形成高速射流以及正向起爆时形成低速射流进行了三维数值模拟 ,计算结果与实验吻合。计算的逆向起爆形成射流头部速度为 8.78km/ s,而正向起爆形成的射流头部速度为 4.86 km/ s。
Jet formations of the shaped charge with a low ratio of length to diameter are simulated by LS DYNA3D code. Simulations with both reverse initiation and normal initiation are performed. Reverse initiation are different with normal initiation in the collapse process and jet velocity. The simulation jet tip velocity with reverse initiation is 8.78 km/s, while with normal initiation it is only 4.86 km/s. The simulation results are in agreements with the experiments. The simulation results provide important data for investigation.
