Abstract
A new structure of annular shaped charge jet was proposed to solve the deficiency of existing annular shaped charge, such as poor stability, lower velocity, etc. Based on the orthogonal optimization method, the influence of liner thickness, radius of curvature of liner, the cone angle of the focusing device, the diameter of the nozzle and the thickness of the shell on axial and radial velocity of jet tip was measured by Autodyn software. A new type of annular shaped jet with high axial velocity and low radial deflection speed was optimized and verified. The experimental results are in good agreement with the numerical simulation results. The numerical simulation and experimental results show that the new annular shaped charge structure proposed in this paper can form an annular hole on steel target, with hole diameter of 107 mm, and depth of 28 mm.
