摘　　要：针对中国人体特征进行损伤生物力学研究的重要目的是为完善中国汽车安全法规提供科学依据.为了深入探讨中国人体损伤生物力学机理和损伤响应,根据中国人体解剖学结构,建立了具有较高精度的中国50百分位成年男性乘员的上肢有限元模型,包括上肢骨骼及关节、韧带、肌肉和皮肤等软组织.针对长骨骨干断面几何不均匀的特征,建立皮质骨不等断面厚度和形状连续变化的长骨数值模型.筛选并汇总国内外尸体实验数据,在准静态和动态加载下验证长骨和上肢模型的可靠性,以及肩关节侧面碰撞响应.结果表明,该模型能准确反映人体上肢损伤特性.The investigation into injury biomechanics of Chinese human body orients to offer scientific data for im-proved Chinese automobile safety regulations. In order to investigate the injury response and mechanism of Chinese human body, a finite element model of the upper limb for Chinese 50th percentile male occupants is constructed based on the anatomical structures by CT scanning. The model is detailed into the bones and the soft tissue （ name-ly the joint, the ligament, the muscle and the skin） of the upper limb. Then,according to the non- uniformity ofthe long bone section, a numerical model of the cortical bone section is constructed by continuously changing thick-ness and shape. Finally, by experimental data summarized from the past mortal human subjects, the reliability ofthis model is verified under the quasi-static and dynamic loading,and the response of the shoulder joint in a sidecollision is also analyzed. The result show^s that the constructed the models can fairly reflect the injury characteris-tics of the upper limb.
