摘要
Abstract
To achieve the linear shaped charge jet with better characteristics, a truncated linear liner with rectangular auxiliary liner charge structure was designed.Six new charge structures and the traditional charge structure were simulated and calculated by the ANSYS/LS-DYNA 3D finite element program.The effect of rectangular auxiliary liner width and truncated gap length on the linear jet characteristics was analyzed.The results show that the maxium velocity of linear jet head formed by this new structure is overall higher than traditional linear shaped charge jet;and the linear jet shape is longer and thinner, the slug is relatively small, and the quality utilization rate of liner is higher.In the six sets of schemes, when the rectangular auxiliary liner width is 1.0cm and truncated gap is 0.4cm, the velocity of linear jet head formed by this structure is the maximum of 3.58km/s with better continuity,maximum effective width.关键词
