摘要
为推动人体胸部有限元模型的构建与仿真应用研究,结合实际场景,针对爆炸、钝性弹道冲击、高速弹道冲击,3种不同场景下的人体胸部有限元模型结构进行了详细分析.由于人体胸部组织的生理结构存在差异,因此,在受到弹道冲击和碰撞时,不同类型的组织会出现不同程度的损伤.对不同场景下的人体胸部有限元模型进行了综合分析,明确了其优劣特点,并提出了一些建议来优化这些模型,以提高其生物保真度和精确度.通过减少事故中胸部组织受损的程度,满足单兵防护等相关领域对人体胸部冲击研究的需求.
Abstract
In order to promote the research on the construction and simulation application of the finite element model of the human chest,the structure of the finite element model of the human chest is analyzed in detail in combination with the actual scenarios,three different scenarios are focused on,namely,explosion,blunt ballistic impact,high-speed ballistic impact.Due to the differences in the physi-ological structure of human chest tissues,different types of tissues will experience different degrees of damage when subjected to ballistic impact and collision.Therefore,a comprehensive analysis of the finite element model of the human chest in different scenarios is carried out,their advantages and disadvan-tages are clarified,and some suggestions are presented to optimize these models to improve their biofidel-ity and accuracy.By reducing the degree of chest tissue damage in accidents,it meets the demand for human chest impact research in related fields such as man-portable protection and others.
