| Abstract: | Pedestrian head protection is studied and a 4.5kg adult headform was built which satisfies GTR requirement. The headform is used to analyze the impact on the windshield with virtual test method, and the effect of different locations impacted and relevant structures on pedestrian head injury evaluation criteria is compared. The results show that the risk of head injury has a significant trend of area distribution. Special design for specific structure will be effective to reduce the risk of head injury. |
