准静态和动态载荷下的人体胸部响应有限元分析

Finite Element Analysis on Human Thorax Responses Under Quasi-static and Dynamic Loading

根据前人文献中的生物材料参数,建立了一个基于人体胸部解剖学结构的有限元模型,并利用该模型,对前人的实验进行仿真,包括对Kallieris的肋骨三点弯曲实验,Li Zuoping的肋骨结构实验和Patrick低速碰撞系列实验的仿真。结果表明,该胸部有限元模型可有效地用于车辆碰撞中的人体胸部损伤生物力学研究。

According to the biological material properties used in predecessors＇ literature, a FE thorax mod- el is developed based on human anatomical structures. With the model a series of simulations on predecessors＇ ex- periments are conducted, including simulations on three-point bending test for ribs performed by Kallieris, the rib structural experiments conducted by Zuoping Li, and Patrick＇s series experiments of low-speed impact. The results indicate that the thorax FE model can be effectively used for biomechanical researches on human thorax injuries in vehicle collisions.
