Numerical Simulation of Influence on Performance of Rod-Liked Jet by Shell

摘要

The performance of Rod-like jet with different thickness of shell is simulated by the finite element dynamic code LS-DYNA3D. The process of formation, elongation and neck of Rod-like jet is shown. The influence of different thickness of shell on performance of Rod-like jet is analyzed, and the Rod-like jet with higher velocity, lower velocity gradient, larger length diameter ratio was obtained. It may be helpful for designing the configuration of shaped charge of Rod-like jet.
