Research on Simulating Optimization of Extended Penetrator
In order to further enhance the penetration merit, the extended structure has been improved and optimized. In this paper, the LS-DYNA code was employed for normal incidence simulation on several extended structures of the same mass. Target material is RHA603 at the speed between 1.47km/s to 1.77km/s. The numerical simulation results show that on the basis of the general extended penetrator of the merit was further improved by add connector structure. While at the speed of 1.57 km/s, transverse reflux was formed by the erosion of material in the course of its penetration. This greatly reduces the penetration efficiency. Then by the addition of plug,it makes the merit of extended penetrator greater stability and efficiency, the maximum merit was up to 18.1%.
