Simulation Study Of A Moving Body In Oblique Penetration Of Shaped Charge Jet

In the modern war, especially in the local war in modern times, with the rapiddevelopment of air missile, a large number of strategic objectives into the underground,Protection of the underground target is more and more strong. But at the same time alsodeveloped a large number of countries to invade earth penetrator underground. According tothe existing technical conditions on the targets of military importance to reinforce.It isdifficult to resist the damage effect of a large number of precision guided weapon penetration.In this context, it is particularly important that the short range antimissile defense as the finalbarrier to protect one’s own goal, and the anti-missile efficiency directly affect the finalvictory. The short range anti-missile warhead is mainly in the form of the Kinetic EnergyInterceptor Based fragment, such as focusing warhead, controllable discrete rod warhead,directional warhead, the less damage effect of deep penetration warhead. Shaped charge jethas the characteristics of high energy, fast speed and penetration effect is good, if the use ofthis type of warhead will greatly improve the efficiency of short range anti-missile. Based onthe deep penetration bomb as the goal, the influence factors of metal jet performance isstudied in detail, based on the analysis of the domestic and foreign related charge, factors andcombined with the moving target on the jet penetration, By using the ANSYS/LS-DYNAfinite element analysis software based on the condition, simulation, comparative analysis ofsimulation results, Selection on the motion of a body in oblique penetration effect is relativelygood medicine type cover structure. The simulation results show that the, have serious effectsof penetrating target motion of the jet; In a certain condition of shaped charge warhead, Thetarget speed is high, influence on the jet penetration increases. In the condition of the targetspeed, conical shaped cone angle of110degrees for the hood penetration effect of jet formedby the moving body best.The work of this paper is the development of reverse deep penetration to provide certain reference for earth penetrating weapon, but also for the short range provides ideas andmethods for anti-missile research.
