The liner structural parameters considered in this paper were the cone angle, wall thickness, fried and initiation point and the parametric effect on Sunder were also analyzed, and finally the Taguchi method step by step analysis was used to study the influence of various factors on jet forming process and find the best solution for effective perforating depth. The results of analysis showed that the initiation point was the most significant factor considered and had nearly 22.61% contribution. The perforated effect decreases as the initiation point move from edge to the center. The wall thickness accounted for 11.09% effect on perforating depth. Based on the results, we can make a better shaped charge liner design in the subsequent application.
