Abstract: In order to study the influence of charge speed on the damage power of explosion shock wave, Autodyn software was used to simulate the deformation of armored steel circular target plate under dynamic explosion shock wave, the theoretical calculation model of central deflection of armored steel circular target plate under dynamic explosion shock wave was established, and the simulation results were compared with the theoretical calculation results. The results show that the overpressure peak of the explosion shock wave along the direction of charge velocity is greatly increased and the propagation speed of the explosion shock wave along the direction of charge velocity is accelerated. The theoretical calculation model can accurately calculate the central deflection of the fixed circular target plate under dynamic explosion shock wave, and has universal applicability.
