摘要: 为推动钝性弹道冲击领域胸部及弹丸有限元模型的构建及验证研究工作,对具有详细解剖结构和类比结构的胸部有限元模型进行了梳理,对比分析了五种典型胸部有限元模型及其验证方法,提炼了典型弹丸有限元模型的构建与验证方法,综述了基于有限元模型的冲击损伤评估方法,通过剖析现有研究的不足给出了下一步的研究建议。后续为提高胸部有限元模型的精确度和生物保真度,需要在尸体实验的基础上,基于同一尸体测量学数据建立物理模型和有限元模型,通过揭示弹-靶能量交互及靶标内应力波的传播规律,深入阐明防暴动能弹的直接损伤和远达损伤机理。

Abstract: In order to promote the construction and verification of the finite element models of human thorax and non-lethal projectiles in the field of blunt ballistic impact, the detailed anatomical and analogous structures of the thorax finite element models are combed and five typical of them are compared and verified. The construction and verification methods of the typical non-lethal projectile models are refined and the impact injury assessment methods are summarized. The next research recommendations are given. In order to improve the accuracy and biological fidelity of the thorax model, it is necessary to establish the physical and finite element model on the measurement data of a same cadaver. By revealing the energy interaction between the projectile and the target and the propagation of the stress wave within the target, the direct and remote injury mechanism of the anti-riot kinetic projectile are illustrated.

Key words: finite element method, anti-riot kinetic projectile, blunt ballistic impact, impact injury mechanism
