摘要

为探究有防

护人员受破片钝性冲击后的损伤风险与背面凹陷（Back Face Signature，BFS）最大深度的动态关系，为精准防护设计提供依据，通过弹道极限试验确定8g钨合金破片对NIJ III级防弹插板的弹道极限速度

为740 m/s。将苯乙烯-乙烯-丁烯-苯乙烯（Styrene Ethylene Butylene Styrene，SEBS）凝胶假人试验与人体有限元模型结合对比，开展破片钝击有防护SEBS凝胶假人试验，同时基于碰撞安全人体整体模型（Total Human Model for Safety，THUMS）构建含右肺、心脏两个冲击位置的有限元模型，以逻辑回归方法绘制损伤风险曲线，结合毁伤树明确损伤判定准则。研究结果表明，心脏是最易受钝击损伤的胸腔器官，不同冲击位置损伤敏感性差异显著，心脏区域损伤阈值（400.3 m/s）低于右肺区域（513.6 m/s），胸骨对非直接钝击的抵抗能力强于肋骨；综合位置特异性后，人员50%损伤风险对应的BFS最大深度为18.47 mm，显著低于传统25 mm阈值，且构建的逻辑回归模型曲线下面积达0.9608，预测准确性优异。研究结论可为战场损伤快速评估及防护装备差异化优化设计提供科学支撑。

Abstract

The dynamic relationship between the injury risk and maximum back face signature (BFS) of protected personnel subjected to blunt fragment impacts is studied to provide a basis for precise protective design. The ballistic limit velocity

of 8 g tungsten alloy fragments penetrating the NIJ III bulletproof plates is determined to be 740 m/s through ballistic limit test. The styrene ethylene butylene styrene (SEBS) gel dummy tests are combined with the finite element human body models for comparison. The blunt impact tests on protected SEBS gel dummies are conducted

and a finite element simulation model including two impact positions (right lung and heart) is established based on the total human model for safety (THUMS). The injury risk curves are plotted using logistic regression

and the injury criteria are clarified with the help of an injury tree. The results show that the heart is the most vulnerable thoracic organ to blunt trauma

and the differences in injury sensitivity between different impact positions are significant:the injury threshold of the cardiac area (400.3 m/s) is lower than that of the right lung area (513.6 m/s)

and the sternum has a stronger resistance to non-direct blunt impacts than the ribs. After considering the positional specificity

the maximum BFS corresponding to a 50% injury risk in personnel is 18.47 mm

which is significantly lower than the tr

aditional threshold of 25 mm. The constructed logistic regression model has excellent prediction accuracy with an area under the curve of 0.960 8.The research conclusions can provide scientific support for the rapid assessment of battlefield injury and the differentiated optimization design of protective equipment.
