Study on the Penetration Performance of Different Shaped DU Alloy

To study the penetration performance of different shapes of a DU alloy fragment, we performed an experiment on a Q235B steel target with a thickness of 20 mm and obtained its terminal ballistic marriage parameters of cylindrical DU alloy fragment penetration.Then, we carried out the corresponding simulation of the key ballistic trajectory using the ANTODYN software.The results from the simulation were found to accord basically with those from the experiment, thereby verifying the simulation results as correct.Furthermore, on the basis of the original simulation, we simulated the cylindrical, cubic and spherical fragments penetrating the target plate with different target positions taken into account.The results show that, in the same quality and at the same velocity, the penetration capability of the cubic fragments in the attitude of the edges and the target cube diminishes in turn with the attitude of the target cube and the spherical fragment, with those in cylindrical and parallel attitude as the weakest.Moreover, hitting the target vertically, the cubic fragment exhibits a stronger penetration than that of the cylindrical, and it shows a better penetration capability when hitting the target in an angular or corrugated attitude.
