Numerical Simulation on the Interaction between Shaped Charge Jets and Confined Explosives
By applying dynamic software 3D LS-DYNA, The shaped charge jet and its penetration into confined explosives is simulated. The simulation results show that: in normal impact, the shaped charge jet disturbed by denotation product which decreased the jet penetration, and in oblique interation, the shaped charge jet cut by moving plate beside disturbed by denotation product. The effect increase with jet entry angle. Introduction The flat surface mezzanine packs target structure of medicine to clip a thin layer between two pieces of lamellas explosive, explosive explosion, drive metal target plank to follow method to fly to spread, the strong interference gathers ability metal shoot to flow or wear A pole body and make of expiration or lower to invade steeping ability. BE considering towards shooting and flowing to bump shot flat surface mezzanine to pack a medicine research winning, generally that shooting to flow is inclined the mezzanine invading steeping flat surface packs a medicine and fly plank with shoot to flow a direct function mutually, strengthened interference effect. When shoot to flow perpendicularity to bump shot and wear deeply lamella at the same time, the explosive drives metal plank to follow method to exercise, in order to flying plank sport direction and shooting to flow a direction parallelism, in the process of exercising in shoot to flow and fly plank don't get in touch with, mainly is an explosion field to have a miscarriage to living a function towards shooting. Figure 1. Shoot to flow to invade sloping flat surface mezzanine to pack medicine model. Figure 2. X-ray that the flat panel transforms lightings. The formation that this literary grace is shot to flow with the 3D limited dollar procedure emulation and invade Steeping process to the Target knothole that puts to have flat surface mezzanine the explosive, the aim forms after analytical explosive explosion of the outcome fly to is over and throw to shoot to accelerate the front-panel is to the influence that shoots to flow to invade Steeping ability.
