摘　　要：为深入研究聚能切割索的切割能力,采用数值仿真和试验的手段研究了聚能切割索(Flexible Linear Shaped Charge,FLSC)切割不同材料铝板的切割效果。仿真和试验结果表明:材料的屈服强度对侵彻性能影响最大,随着被切割对象屈服强度的增大,侵彻深度降低。Material separation mechanisms are studied from the view point of cutting ability of flexible linear shaped charge.The effect of flexible linear shaped charge cutting different aluminum is analyzed by numerical simulation and experiment method.The simulation and experiment results proved that the material yield intension is the main complication for penetration performance.The penetration depth induces with the increasing of the yield strength of the cutting target.
