摘要

为提高聚能射流的侵彻能力,结合射流的二次喷射现象,在锥角药型罩基础上设计出V形顶部结构药型罩,运用ANSYS/LS-DYNA对V形顶部药型罩的射流形成和射流侵彻靶板过程进行数值仿真并与锥角药型罩的侵彻能力进行对比。结果表明:V形顶部药型罩的射流头部速度比锥角罩提高约7.2%,射流没有断裂,延展性好,且杵体较小。V形顶部药型罩形成的射流的侵彻深度提高约16.9%,侵彻能力更强。

Abstract

In order to improve the penetration performance of the shaped energy jet, a V-shaped top structure liner was designed based on the cone liner by using a secondary jet phenomenon of the jet, and the jet formation of a V-shaped top structure liner was performed by ANSYS/LS-DYNA. The process of jet penetration into the target was numerically simulated and compared to the cone liner. The results suggest that the jet head velocity formed by the V-shaped liner is about 7.2% higher than that of the cone liner. The jet is not broken, the ductility is good, and the slug is small. The penetration depth of the jet formed by the V-shaped top structure liner is improved by about 16.9%, and the penetration performance is stronger.

Key words： explosion mechanics; shaped charge; V-shaped top structure liner; numerical simulation
