Abstract

This paper will describe head impact studies on hood of vehicles using headform impactors and engine compartment Finite Element (FE) models. A commercial FE code PAM-CRASHTM was used to conduct the computational simulation. Head Injury Criteria (HIC), which is obtained by post-processing the computed acceleration history, is used in this prediction method. Several numerical examples are demonstrated where close agreement between the test and the calculated values of the acceleration history is obtained. Additionally, the numerical scattering analysis is implemented to clarify the importance of each parameter.
