Abstract： Aiming at the steel engine hood coudn't meet the requiements of pedestrian impact protection regulation，the steel materials were insteaded by aluminum and the structures were redesigned to the engine hood. The finite element model of head block and engine hood were built in ANSYS. Through the comparison between finite element simulation and test results， the reliability of the finite element model was proved. The finite element simulation analysis was done to the newly designed wave type aluminum engine hood and the original beam type steel engine hood. The comparison results show that the newly designed structure can effectively reduce pedestrian head injury criterion，meet the pedestrian impact head protection standard.
