To further improve effective jet of liner and depth of steel target penetration, five structures of series liner were designed by different center cylindrical height. Numerical simulation of different center cylindrical height of liner series' jet forming and the penetration of steel targets was done with the finite element software LS-DYNA, then accompanied by the appropriate test of explosive charge. Essential analysis and conclusion have been drawn out. It can be concluded from the results that the velocity of front jet formed by the charge structure with proper center cylinder height is higher that the one with too high or too low center cylinder height, and the penetration of the former is deeper, the numerical simulation basically agrees with the experimental study.
