为了得到爆炸载荷下导弹结构的毁伤特性,基于ANSYS/LS-DYNA软件将导弹目标简化为由壳体、框架和内部配重组成的简单结构,对爆炸载荷单独作用和爆炸载荷与破片联合作用下导弹结构的毁伤变形过程进行了数值模拟,得到了导弹壳体、框架和内部配重的变形特征,为战斗部设计和目标易损性评估提供了参考。

In order to get damage characteristics of missile's structure under blast load, the commercial FEM program was used to simulate the deformation process of missile target. The missile target was simplified as a strucutre composed of case, frame and internal counterweight. The damage characteristics of missile's case, frame and internal counterweight were got, providing reference for the design of warhead design and target vulnerability assessment.
