一种新型M形顶部结构药型罩的设计及形成射流的侵彻能力分析
Design of A New M-shaped Top Structrue Liner and Analysis of Penetration Ability of Its Jet Formation
摘要
Abstract
Based on the liner structrues of the cone angle, a new liner structure with M-shaped top structure was designed by changing its top structure, and the formation mechanism of its jet head was analyzed.The numerical simulation of jet formationin process of liner with M-shaped top structrue under the action of detonation wave and the penetration process of No.45 steel plate was performed by using the finite element software ANSYS/LS-dyna, and comparison with the head and end velocity, stretching length, slug size and the penetration ability of No.45 steel plate of the jet formed by the cone angle liner and the flat-top liner was performed.The results show that the top structure of the liner with M-shaped top structure forms jet head at two times convergence under the action of detonation wave.Under the same loading condition, compared with the cone angle liner jet-forming head speed, the M-shaped liner jet-forming head speed is increased by about 9.10% and the flat-top liner jet-forming head speed is increased by about 5.56%, its penetration depth is improved by about 10.40% compared with the cone angle liner, its penetration depth is improved by about 7.28% compared with the flat-top liner liner.关键词
