| 摘要： | Pedestrian protection is a research focus in the field of automotive safety.In order to improve the study of injure biomechanics and pedestrian protection, many investigators both at home and abroad have developed FE models for pedestrians according to foreign data.But most of them are not suitable to Chinese pedestrians because of the difference between Chinese and foreigners.Based on the CT scans of 50th percentile Chinese male volunteer, this paper developed a finite element model of lower extremity with good biomechanical properties.The FE model contained major anatomical structures of human lower limb, such as femur, tibia, fibula, patella, hip and knee-joint.Especially, the knee-joint model included important soft tissues such as ligaments, meniscus and capsule.The bones were modeled with hexahedral solid elements, included cortical and trabecular layers; the ligaments were modeled with quadrilateral shell elements.Both the bone models and ligament models were defined failure to model the fracture of bones and the tear of ligaments.The model developed in this study was compared with other models developed by Untaroiu(2004),Takahashi(2000), etc.As with other models, this model has high biofidelity.The FE Model of lower extremity can be used in the research of injure biomechanics for Chinese pedestrians in traffic accidents. |
