    Abstract
  • To improve the performance of linear shaped charge jet, this study applies the truncated and auxiliary liner structure to the linear shaped charge.The three-dimensional finite element analysis software (LS-DYNA) was used to simulate the linear shaped charge jet formed with copper as the main liner and Al, Cu and W as auxiliary liner.At the same time, comparison between the formed linear shaped charge jet and the traditional jet is performed, indicating that the jet formed by the truncated and auxiliary liner structure has better performance.With the increase of the density and hardness of the auxiliary liner material, the jet's ductility, speed and effective mass are improved and all of them are superior to the traditional wedge cover structure.Compared with the conventional wedge cover structure, the speed and the effective length of the jet utilizing W as the auxiliary material increase about 25.9% and 145%, respectively.
