    Abstract
  • The influence of structural parameters (liner cone and thickness) of dual-mode warhead on the forming performance of dual-mode damage element is studied by LS-DYNA for the miniaturization design and application of dual-mode warhead, and the results reveal that the head speed of dual-mode damage element obviously decreases with the increase of liner cone and thickness. By the orthogonal design method, it is found that the thickness of the liner is the main factor to determine the head velocity difference between the two damage elements, and the liner cone is the main factor to determine the head velocity of each damage element. The structural parameters combination of the liner is obtained as following, whose forming performance of the dual-mode damage element is better. The liner cone is 80°, the thickness of the upper end of the liner is 5.0 mm, the thickness of the lower end of the liner is 4.0 mm, and the liner radian radius is 10.0 mm. X-ray imaging tests were done, whose results show a quantitatively good agreement between numerical simulation and tests. The research results provide a reference for the further optimization design of the dual-mode warhead.
