Research on armour-piercing effect of high velocity tungsten alloy fragment against medium-thick steel target

The armour-piercing effect of high velocity tungsten alloy fragment against medium-thick target was studied. The high velocity uprightness armour-piercing experiment of φ7.0 mm tungsten alloy ball against 15 mm and 20 mm Q235 steel was done to get the ballistic limiting velocities or perforation depth of tungsten alloy fragments; base on the experiment, the simulation parameters were demarcated; the ballistic limiting velocities or perforation depth of tungsten alloy fragments with difference size and structures were obtained by the numerical simulation; the influence of fragment structure and velocity on armour-piercing effect was analyzed and discussed. The researched results provide basis for the optimized design and the power evaluation of the relative performed fragment warhead, and the research idea and way can be used as a source of reference for other correlation research.
