This article deals with a simulation of the influence of double cone liner shape on the jet characteristics of a small-sized shaped charge by ANSYS AUTODYN software. The results prove that, with a smaller apex angle, a smaller base angle, and a larger distance from the top of the liner to the transition position of the cone angle, the jet velocity and jet length will be larger. For a 40 mm shaped charge used in the study, a double cone liner with shape parameters including an apex angle of 40°, a base angle of 60°, and a cone angle transition position from the top of the liner at a value equal to 0.3 times, the base diameter is predicted to provide the best jet performance. The research results are the basis for evaluating the influence of liner shape on the jet formation process and designing a double cone liner for small-sized shaped charges.
