Abstract

In order to investigate injury mechanisms, and to provide directions for road safety system improvements, the HUMOS project has lead to the development of a 3D finite element model of the human body in driving position. The model geometry was obtained from a 50th percentile adult male. It includes the description of all compact and trabecular bones, ligaments, tendons, skin, muscles and internal organs. Material properties were based on literature data and specific experiments performed for the project. The validation of the HUMOS model was first achieved on isolated segments and then on the whole model in both frontal and lateral impact situations. HUMOS responses were in good agreement with the experimental data used in the model validation and offers now a wide range of applications from crash simulation, optimization of safety systems, to biomedical and ergonomics.

摘要

为了研究损伤机制,并为道路安全系统的改进提供指导,HUMOS项目促成了一个处于驾驶位置的人体三维有限元模型的开发。该模型的几何形状取自一名第50百分位的成年男性。它包括对所有密质骨和松质骨、韧带、肌腱、皮肤、肌肉和内部器官的描述。材料特性基于文献数据和为本项目进行的特定实验。HUMOS模型首先在孤立节段上进行了验证,然后在正面和侧面碰撞情况下对整个模型进行了验证。HUMOS的响应与模型验证中使用的实验数据高度吻合,目前在从碰撞模拟、安全系统优化到生物医学和人体工程学等广泛领域都有应用。
