Development and validation of a 6-year-old pedestrian thorax and abdomen finite element model and impact injury analysis
A detailed anatomy structure finite element (FE) model of the paediatric thorax and abdomen of a 6-year-old was constructed and validated. The thoracoabdominal geometrical model, extracted from computed tomography (CT) scan images of a 6-year-old child, was divided into finite element models with different types of elements. The validity of the model was verified by reconstructing impact experiments of paediatric cadaver thorax and abdomen and comparing impact force-deformation curves, maximum viscous criterion (VC) values and tissue injuries between simulations and experiments. The simulation results showed that the thoracoabdominal impact force-deformation curves located in the experimental corridors, and the trend of the curves, was well consistent with the experimental corridors. The maximum viscous criterion values in simulations were also located in the range of experimental results. Injuries to ribs and internal organs predicted in simulations were consistent with the autopsy results. Therefore, the model can be used to study the mechanism of child pedestrians' thoracic and abdominal injury in traffic accidents. Language: en
期刊介绍：
The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
