    Abstract
  • In order to enable warhead to have multiple directional damage modes and to achieve a certain degree of controllable damage, a deformable directional fragment warhead with fan-shaped charge is proposed. It can realize an axial-expanding mode and an lateral-expanding mode. The AUTODYN software is used to carry out the numerical simulation of the fragment field. Firstly, the position of the initiation point at 25 mm away from the central axis is determined based on the analysis of the unit constituting the warhead. Secondly, for the axial-expanding mode, the influence of the axial-expansion angle on the fragment flying speed, the quantity and the spatial distribution of fragments are obtained. The results show that the damage effect of the warhead is better when the axial-expansion angle is in the range of 60°–75°. Thirdly, for the lateral-expansion mode, the velocity and the spatial distribution of fregments are analyzed. It showes that the fragments under the lateral-expansion mode have directional flying quality.
