文摘

Child pedestrian protection deserves more attention in vehicle safety design since they are the most vulnerable road users who face the highest mortality rate. A computationally efficient six-year-old (6YO) pedestrian finite element (FE) model was developed and validated based on the latest published pediatric data. The bone models assigned pediatric material properties showed lower stiffness than the models assigned adult material properties and a good match to the test data. Overall, the 6YO FE model developed in this study showed good biofidelity at component level (lower extremity and pelvis) and stability in the FE simulations of car-to-pedestrian collisions (CPC).
