Abstract

In order to explore the influence of three factors, including the radius of ball missing curvature, length-diameter ratio of charge and shell thickness, on the average fragment Angle of axial focused prefabricated fragment warhead with ball missing arrangement, the numerical simulation of fragment warhead was carried out by using LS-DYNA software. The results show that the average fragment scatter angle decreases first and then increases with the increase of the ball missing curvature and the length-diameter ratio of charge. With the increase of shell thickness, it firstly decreases and then tends to be basically stable. Using the orthogonal design method, the primary and secondary relations of three factors affecting the average dispersive angle of fragments are analyzed. The results show that the spherical curvature radius has the greatest influence, followed by the shell thickness, and the length-diameter ratio has the least influence. The optimal combination of the three factors is obtained.

Key words： axial prefabricated fragment; flying angle; orthogonal optimization; the numerical simulation
