导弹弹体空中结构解体毁伤研究

Damage Study on the Missile’s Body Structure Disaggregation in the Air

针对弹体结构解体破坏是导弹K级毁伤主要毁伤模式之一，进行了爆炸冲击波载荷作用下自由状态导弹弹体结构毁伤理论预测与实验验证。基于简化的弹体质量阶梯分布梁结构和能量分析，进行了导弹弹体结构解体毁伤临界冲量理论预测，通过爆炸冲击载荷作用下局部及舱段式弹体摸拟结构毁伤实验，对理论模型进行了分析验证。研究结果对于导弹目标易损性分析与毁伤评估具有一定参考价值。

Theoretical prediction and verified experiments of body structure damage of the missiles have been performed to tackle the problem, that is, the body structure disaggregation damage being one of the main damage modes of K level damage of the missiles. And based on the simplified stepped mass distribution beam and energy analysis, critical impulse resulting in structure disaggregateion of the missile body has been calculated. Then, experiments of simulated body structure damaged under the blast loadings were conducted, which included local and compartment body structure. Studied results are of great significance to vulnerability analysis and damage assessment of the cruise missile.
