FEA of helmet-head injury protection based on motorcycle accident reconstruction
Paper i proceeding, 2013

Head impact usually causes fatalities of riders in motorcycle accidents. The use of helmet can protect head effectively and the study of head injury mechanism is useful in safety helmet design and head injury risk decrease. A real motorcycle-passenger car accident was reconstructed in order to simulate and analyze the motion, impact velocity, impact angle in the collision. In order to study the dynamic response of helmeted head during the accident impact processing, an effective helmet model was constructed and validated. Coupling with the finite element model of human head, the injury mechanism of head and relevant parameters of biomechanics were studied and the protection ability of helmet was analyzed. It was found that the presence of helmet reduces the probility of head injury.
