| 摘 要： | 为了优化设计用于串联战斗部前端的环形切割器,通过ANSYS进行环形切割器建模,利用LS-DY-NA对相等装药条件下多个药型罩开口角度方案、三种装药形状的环形切割器对靶板的切割效果进行后效仿真分析。仿真结论表明,60°锥角、柱锥体装药形状的环形切割器对靶板的切割效果更为理想。通过与相关试验数据的对比,初步验证了数值仿真的准确性。该结论有助于新型环形切割器的优化设计。

Optimum Design on Annular Cutter of Tandem Warhead |

| 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. |
