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模拟结构毁伤实验,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。 In view of the disintegration and destruction of projectile structure, it is one of the major damage modes of missile K-class damage. Theoretical predictions and experimental verifications of the projectile structure damage of free-state missile under blast shock loading are carried out. Based on the simplified structure and energy analysis of the projectile with mass ladder, the theoretical predictions of the critical impulse of the projectile structure disintegration damage are carried out. By the experimental results, Analysis and verification. The research results have certain reference value for missile vulnerability assessment and damage assessment.
