Abstract

Abstract

To improve the steel target penetrating capability of the rod-like jet, we designed an eccentric semispherical liner. The liner's collapsing velocity was deduced by detonation wave collision theory, and the rod-like jet formation model was established by combining the improved PER theory. The laws determining how the liner configuration parameters affect the detonation wave collision pressure were drawn out, and the jet mass and velocity distribution laws were obtained by changing the thickness of the equal mass liner. Our test results show that the Mach collision pressure increased with the increase of the eccentric distance, and decreased with the increase of the ectotheca curvature radius. Moreover, the variation law of the regular oblique reflection pressure was reverse with the Mach collision, which was greatly affected by the liner configuration. By comparing different schemes, we find that the jet mass of the liner, which was thick at the top and the bottom but thin in the middle, increased by 29.5%, and the tip velocity increased by 21.3%, while, with the maximum velocity gradient and the same condition of standoff distance, the penetration depth almost doubled the charge caliber. The simulation and experiment were carried out aiming at the optimal configuration, and the formation and penetration performance of the rod-like jet was improved remarkably through the optimum matching of the detonation wave form with the liner configuration.
