Uniform Design on the Forward Annular Shaped Charge of Torpedo Tandem Warhead

By using LS-DYNA 3D software, the structure of forward annular shaped charge of torpedo tandem warhead is optimized in the simulation with uniform design method. During the simulation of annular shaped charge penetration into the plate underwater, the liner opening angle,liner thickness,charge height and charge angle are taken as factors, while the penetration depth is taken as index. The optimized structure parameters resulted form simulation can be used in the design of torpedo.
