- Here, the pedestrian lower extremity injury risk was studied using the real world accident data. For this purpose, 354 cases with pedestrian lower extremity injuries selected from the german in-depth accident study(GIDAS) database were used to conduct the one-way variance analysis to determine the effects of impact speed, pedestrian age, height and weight on the pedestrian serious lower extremity injuries risk. Then, the pedestrian serious lower extremity injury risk model was established. The results showed that the impact speed and pedestrian age are significant factors affecting pedestrian lower extremity serious injuries, but the pedestrian weight and height are not; the risk of injury is positively related to impact speed and pedestrian age; the pedestrian serious lower extremity injury risk reaches 50% when the impact speed is 43 km/h.

- The purpose of the current study was to analyze the influence of changes of the material of the human thoracic skeleton and soft tissues on the thorax responses under frontal impact loading conditions. A series of human thorax impact simulations were conducted based on a developed and validated human thorax finite element (FE) model. A number of thoracic response parameters were output to investigate the effect of material property changes on the predicted thoracic responses by using polynomial fitting analysis. The results of the simulations indicated that varying thoracic material properties affects the impact responses with different level. The impact force (Fmax) and chest deflection (Dmax) were obviously affected, and the number of rib fractures (NRF) and T12 accelerations (Gmax-T12) were additionally affected by the material properties. However, the influences of the material properties on the deflection rate (Vmax) and T1 acceleration (Gmax-T1) were small. Specifically, the Fmax, Dmax, and Gmax-T12 were mainly influenced by the soft tissue material properties, while the NRF was primarily determined by the thoracic skeletal structure material properties.
