Abstract

In order to study the effects of liner configuration parameter on formation of K-charge, the ANSYS/LS-DYNA software was used to simulate the formation process of projectile, and the effects of the formation process and charge structure on the head velocity, velocity gradient, length and kinetic energy of the projectile were analyzed, and comparison was made to analyze the difference between the charges with detonation wave controller and non-detonation wave controller. The results shows that while length 40 mm <H < 60 mm, curvature radius 300 mm <R <500 mm, thickness 3 mm <δ <5 mm, charge slenderness rate0.7 < x <0.9, the penetration capability of projectile is better. For the small length-diameter ratio charge, appropriate detonation wave controller can be applied to the charge to enhance the speed, length-diameter ratio, energy of projectile. The energy utilization rate of the projectile with detonation wave controller is 17.6%, the speed is 42.5% advanced, the energy is 2.5 enhanced, and the length-diameter ratio is 1 time.
