爆炸冲击波下导弹结构动力分析模型初步研究

针对爆炸冲击波对导弹目标毁伤这一复杂问题进行了合理的简化，研究了冲击波对导弹结构的破坏问题。利用动力学知识,估计了冲击波对导弹目标的机械破坏作用。在综合考虑战斗部装药质量、爆炸点距目标距离、爆炸高度的环境压力、目标几何尺寸以及目标抗冲击载荷能力等基础上，利用自行编制的程序进行了一系列的仿真计算，得出了战斗部在不同时间不同位置和不同装药质量下产生的冲击波对导弹产生的破坏。计算结果基本符合物理规律，说明采用的模型及算法是合理的，能够对目标在爆炸冲击波超压作用下的易损性进行评估，得到的计算结果对实际应用具有参考价值。

A preliminary investigation on dynamic analysis models for missile structures subjected to blast wave

The complex problem on damage experienced by missile projects impacted by blast wave was simplified to explore the damage mechanism of the missile structures.Mechanical damage of missile projects was estimated with the dynamics knowledge.A numerical code was developed by taking charge mass of the warhead,the distance between the explosion point and the missile,the surrounding pressure at the explosion altitude,the geometry size of the missile,and the performance of the missile against shock loading into acc...
