Numerical simulation of shock initiation characteristics of fusion detonators

Abstract To provide an economic and safe destruction program, this paper is based on the jet detonation method of poly energy charge structure design. The use of simulation software is to establish the diameter of the 40 mm polymer charge physical model, and the combat structure model is used for the invasion and detonation simulation calculations. The results show that the theoretical calculations and simulations are in good agreement and the structure can penetrate the 40 mm thick 50SiMnVB shell, to observe the shock wave in the shielding cover and shielding explosives between the transmission process, finding that the thickness of the shell affects the impact detonation mechanism.
