Abstract

In order to optimize the annular cutter of missile tandem warhead, the model of annular cutter is made by ANSYS, and LS-DYNA is used to simulate the cut effects for steel plate of annular cutter at equal charge weight, different open angle and different charge shape. The results shows the annular cutter with 60° open angle and columned pyramidal charge shape have better cut effect to steel plate. According to the comparison with corresponding experimental results, the correctness of numerical simulation model is primary proved. The results help to optimum design on newly cutter.

Key words： shaped charge; numerical simulation; annular cutter; optimum design; jet
