不同初速弹丸对靶板的损伤仿真与评估

为了研究弹丸对武器装备的损伤,建立弹丸侵彻多层靶板的有限元模型,对不同初速弹丸侵彻多层靶板进行仿真试验,引入等效应变及等效应力参量以精确描述靶板损伤,提出一种基于多元统计分析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能够正确地评价仿真实验中目标靶板的战损程度,因而可以进一步应用于装备侵彻损伤评估与易损性研究中。

Simulation and Assessment of Plates Damaged by Projectiles with Different Velocity

In order to study the damage on weapon equipment by projectile,a finite element model is established to simulate the different velocity projectile penetrating multi-layered plates and 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.The assessment result by using this method is proved to be agreeable with the theoretic result.Therefore,thi...
