Abstract：Abstract：By using ANSYS/LS-DYNA, the deforming process of the aimable warhead of premade fragment and the projectile process of its fragments were numerically simulated; finally, the scattering velocity, scattering angle and density in different distance of fragments are 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 fragments 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 computed the target position, the aimable warhead can adopted firstly by the further air defense missile. Otherwise, the contact surface to surface is suitable for the aimable warhead of double-layer premade fragment.
