A stepped liner was designed for the forward charge structure of tandem warhead giving consideration to large penetration depth and bearizing.The numerical simulation method was used to study the formation mechanism of stepped liner jet and the penetration ability to No.45 steel, and compared with the jet parameters formed by conical angle liner and penetration depth and reaming size to No.45 steel.The results show that in the same loading condition, the penetration depth of the stepped liner is about 25％ higher than that of the cone angle liner, and the diameter of the reaming to No.45 steel is about 1.5 times larger than that of the cone shaped liner.Moreover, the stepped liner have a smaller slug, which is more in line with the characteristics of the forward charge structure of tandem warhead.
