Abstract

Abstract: A finite element model of warhead and a calculation model of ground coordinate of a fragment are established to give full play to the air burst power of antipersonnel warhead, and the dynamic detonation of warhead is numerically simulated by using ANSYS/LS-DYNA software. According to the initial velocity and flying direction of fragments in simulation, the velocity attenuation formula of fragment in air and the 78 J killing criterion of personnel, the coordinates of the effective lethal fragment on the ground are calculated, and the distribution of the effective lethal fragments on the ground targets at different burst heights is analyzed. The results show that the warhead meets the lethality requirements when burst height is about 8 m. The experimental results are in good agreement with the simulated results. Key
