  • 摘要: 旨在研究不同碰撞载荷条件下基于不同失效模型的人体肋骨骨折机理. 为此采用已验证的人体有限元胸部模型来分析人体肋骨骨折现象. 该模型基于人体解剖学结构,包含了人体胸椎、腰椎、肋骨、胸骨、肋间软骨、胸腹部器官和其他的软组织,定义的生物材料参数都基于已有的文献记载. 基于人体在损伤生物力学领域内一些较为典型的肋骨骨折失效模型,根据已发表文献中的人体标本实验载荷条件模拟了人体肋骨结构在不同冲击载荷下的骨折现象,并与这些实验结果进行了对比分析. 所引用的实验结果包括单根肋骨强度结构实验和人体胸部正面碰撞块冲击实验. 从文中有限元仿真分析的结果来看,针对不同的载荷条件,不同肋骨骨折失效模型的适用性各不相同. 该人体胸部有限元模型可用于车辆交通事故中冲击载荷条件下的人体肋骨损伤生物力学研究.
