人体下肢三维有限元模型在交通损伤中的应用研究进展

Progress in 3D Finite Element Modeling of Pedestrian Lower Limb Injury

下肢损伤在交通损伤中仅次于头部损伤位居第二,给社会和家庭造成沉重的负担。下肢有限元仿真模型的发展,为交通事故中下肢损伤机理研究和汽车结构参数优化提供了强有力的工具,与其它研究方法相比具有显著的优势。我国下肢有限元模型的发展尚处于起步阶段。针对国内外近20年下肢有限元模型的发展做了论述,并提出了今后构建高生物仿真度的下肢模型需要解决的问题。

The lower extremity injury ranks second only to the head injury and brings a heavy burden on families and society. The development of finite element models for the lower limb, which has obvious advantages over other models, promotes the research on mechanisms of lower limb injuries and on automotive structural parameter optimization. The development of lower limb model in our country is still in its infancy. The paper presents the development of the lower limb model at borne and abroad over the past 20 years. The recommendations for the future research on constructing highly imitative biological models are discussed.
