Numerical simulation and experiment on aimable warhead of premade fragment

By using ANSYS/LS-DYNA, the deforming process of aimable warhead of premade fragment and the projectile process of fragments were numerically simulated. The scattering velocity, scattering angle and density of fragments at different distance were obtained. By the way, an experiment of explosion was carried out to validate the design of the aimable warhead. It reveals that the scattering velocity and the density of the aimable warhead's fragments are high and the scattering angle is fixed. So, when the missile can exactly detect the target and accurately compute the target position, it is superior to adopt, the aimable warhead in the future design of air defense missile.
