摘　　要：针对非致命防暴动能弹对人体的侵彻致伤效应,以明胶为目标靶,建立数值计算模型,对弹丸侵彻毁伤明胶靶过程进行仿真分析,计算结果表明,弹丸对明胶靶的损伤主要集中在侵彻弹道附近,靶体的伤道入口形成外扩隆起;同时对致伤效应进行分析,在Ⅱ级损伤标准下,随着弹丸比动能的增加,目标靶的损伤弹道深度以及创口面积、损伤体积随之增加,且与比动能呈现线性关系,获得损伤的NSDI评分。研究结果可为非致命弹药的设计及评估提供参考。Aiming at the penetration effect of non-lethal anti-riot kinetic energy projectile on human body,a numerical calculation model was established with gelatin as the target,and simulate the process of pellet penetration and damage to gelatin target.The calculation results showed that the damage of pellet to gelatin target was mainly concentrated near the penetration trajectory.The wound entrance of the target formed an external swelling bulge.At the same time,the damage effect was analyzed.Under the levelⅡdamage standard,with the increase of the specific kinetic energy of the projectile,the damage ballistic depth of the target,the wound area and the damage volume increased,and there was a linear relationship with the specific kinetic energy,and the NSDI score of the damage was obtained.The results can provide reference for the design and evaluation of non-lethal ammunition.
