Simulation research on the effect of the liner structure onpenetration capability of linear shaped charge
In order to study the influence of the structure of linear shaped charge,the finite element software LS-DYNA was used to simulate the process of linear shaped charge penetrating the 45 steel with different truncation heights of conical,flat and domed structures.The results show that:the shape and penetration performance of the linear shaped charge jet are greatly affected by the different structure of the linear shaped charge liner;The flat top linear shaped charge has optimum penetration performance at truncation height of 16 mm,with a 6.3% increase in maximum depth of penetration compared to the conical top structure;The domed top linear shaped charge has optimum penetration performance at a truncation height of 10 mm,with a 15.6% increase in maximum penetration depth compared to the conical structure.
