摘要
为了得到定量装药的爆炸冲击波对目标有效毁伤的临界距离。基于LS/DYNA软件,把导弹类目标简化成一定厚度的圆柱壳体,对定量炸药爆炸冲击波毁伤不同距离处的圆柱壳体进行了三维数值模拟,分析了不同距离处爆炸冲击波对壳体毁伤的作用方式和壳体的响应特征,得出了壳体不同的毁伤程度,得到了一定装药下爆炸冲击波毁伤目标的临界距离,为战斗部设计、毁伤评估及目标防护设计等提供参考。
The non-linear dynamical finite element method was applied to simulate the damage effect of air target subjected to blast wave. The missile target was simplified as a cylindrical shell. Blast wave in air generated and the cylindrical shell damaged by blast wave at different distance was simulated using commercial FEM program LS/DYNA. The methods of the blast wave damaging the cylindrical shell were discussed, and then the dynamic responses and damage degree of cylindrical shell subjected to blast wave were studied. The simulation results provide important reference for warhead design of and damage evaluation.
