聚能装药逆向环形起爆射流形成的数值计算
Numerical Computations of Shaped Charge Jet with Reverse Initiation at Liner Base
摘要
Abstract
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 8.78km/s, while with normal initiation it is only 4.86km/s. The simulation results are in agreements with the experiments. The simulation results provide important data for investigation.关键词
