Simulation of jet forming and penetration performance of a new type of shaped charge warhead
In order to improve the penetration ability of a shaped charge warhead to armor in a limited warhead space,a new shaped charge warhead structure with waveshaper-liner linked was proposed.The new shaped charge warhead structure was numerically simulated by LS-DYNA software,and the influence of four shaped hood structure factors on the jet forming morphology was explored by orthogonal optimization design.The results show that the optimal shaped hood structure parameters are upper cone angle 2α=24°,lower cone angle 2β=90°,liner wall thickness t=2 mm,and the upper and lower shaped hood caliber ratio d/D=0.4.When the blast height is 3 times the charge diameter,the maximum penetration depth to 45# steel target plate can reach 686.2 mm.The research results have certain guiding significance for the design of shaped charge warhead.
