爆炸冲击波对靶板的损伤仿真与评估研究

为了研究爆炸冲击波对武器装备的损伤，建立了炸药爆炸冲击靶板的有限元模型，对不同厚度靶板在确定爆炸冲击环境下的损伤进行了仿真试验。不同于传统的宏观破口尺寸损伤表征参数，引入了等效塑性应变来精确描述靶板损伤，并提出了一种基于主成分分析理论对靶板损伤进行评估的方法。结果表明：利用该方法所得到的计算结果与理论分析结果完全一致。这说明基于多元统计分析的靶板损伤评估方法是切实可行的，可以进一步应用于装备爆炸损伤评估与易损性研究中。

Simulation and Assessment of Target Plates Damage by Shock Wave of Certain Explosion

In order to study the damage on weapon equipment by shock wave of certain explosive,a finite element model is established to simulate the damage of target plates with different thickness under the condition of certain explosion.Unlike the traditional macro-level parameter-crevasse size,the amplitude of equivalent stress and equivalent strain is introduced to characterize the target plates damage.By using multivariate statistical analysis,an assessment method of multi-layered plates damage is presented.It is...
