In shaped charge, the detonation control structure parameters of the charge has important influences on the propagation of detonation wave and the formation of dual mode damage element, the influences and regulars of partition′s structure parameters(partition′s diameter, partition′s thickness, partition′s cone angle) and charge′s structure parameters(charge′s height and small explosive column′s height) on the formation of explosive formed projectile (EFP) and jetting projectile charge (JPC) dual mode damage element under the condition of 110 mm charge caliber and JH-2 explosive were researched using LS-DYNA simulation software.The optimal range of the parameters was determined, among them, partition′s diameter and thickness are taken for 0.8-0.87 and 0.05-0.09 times of charge caliber, respectively, partition′s cone angle is taken for 52°-60°, the charge′s height and small explosive column′s height are taken for 1.1-1.2 and 0.06-0.12 times of charge caliber, respectively.Combining with the orthogonal optimizing design method, the best parameter′s group of the charge detonation structure was determined : the diameter, thickness and cone angle of partition were taken for 0.91, 0.07 times of charge caliber and 52°, respectivel.Charge′s height and small explosive column′s height were taken for 1.14 and 0.1 times of charge caliber, respectively, the thickness of shell was taken for 0.09 times of charge caliber.X light photographic test was carried out, revealing that the simulation results are in good agreement with the experimental ones.
