Abstract:In order to study the damage effectiveness of the shaped warhead in air defense and anti-missile, the equivalent target was demonstrated and the charge structure design was introduced, numerical calculation schemes were given, and 3 kinds of typical penetration bodies penetrated equivalent moving target plate at different angles by AUTODYN software for numerical simulation. The results show that the relative motion of the penetration bodies and the equivalent target plate affects the damage efficiency, and there is a reverse stacking effect of the open pit volume. At the same time, the jet is more easily perturbed by the equivalent target plate, and the damage performance by the JPC is better, the EFP opening diameter is bigger but lack of penetration depth.
