人体易损性建模及其评估技术研究

考虑人体结构的复杂性、非均质性，提出了建立具有解剖学结构的人体组织几何模型及其相应的损伤评估算法。利用CVH数据集，应用Photoshop和Matlab建立了基本单位为2mm的立方体、包含123种人体主要组织器官，约652万个单元的高分辨率人体易损性模型。根据实验数据，建立了常规枪弹破片不同速度下侵彻人体形成典型瞬时空腔模型，提出了基于解剖学的损伤评估算法SDI、CDI和NISS。运用HVAssess人体易损性计算程序，获得了典型杀伤元侵彻人体时，各器官的损伤情况，并绘制了损伤分布图。结果表明具有解剖学结构人体易损性模型可用于枪弹、破片侵彻下人体损伤评估，评估结果可为轻武器弹药杀伤效能评价和人体防护设计提供依据。

Study on Human Vulnerability Modeling and Assessment Technology

Considering the complexity and heterogeneity of human anatomy,human body vulnerability model with anatomical structures and assessment algorithm was proposed. based on the CVH( Chinese Visible Human)data set and using Photoshop and Matlab,high-resolution model of human vulnerability was constructed. It contains 123 kinds of human tissues and about 6. 52 million cube units which length is 2 mm. based on experiment data,the typical cavity model of bullet penetrating body at different speeds was established. Injury assessment algorithm SDI,CDI and NISS were proposed. Using the vulnerability calculation program HVAssess,injury level and distribution diagram of organs was obtained when typical kill elements penetrate body. The result shows that human body vulnerability model with anatomical structural could be used to human body injury assessment under bullets and fragments penetrating. Assessment results could provide a basis for weapon effectiveness evaluation,human body protection design and survivability design.
