Fe Modeling Of The Composite Laminate Panel Structure Of The Vehicle Hood To Mitigate The Impact Injury Of The Head
The increased number of pedestrian injuries and fatal deaths are resulting from road accidents due to the increased
urban population and number of private vehicles. In order to address this issue along with other safety measurements, design
and materials of engine hood has been a key point for an automotive industry. In this study, the finite element models of the
pedestrian adult head form and a composite laminate panel of the vehicle hood were created by ABAQUS/Explicit to predict
the level safety of structures for pedestrian during a collision. The effects of different stacking sequences and the inclination
angle of the hood laminate panel to HIC value, deformation and absorbed energy were investigated and discussed.
Simulation results are validated by Euro-NCAP pedestrian head form impact to composite laminate panel. The results show
that the FEM modeling of the composite laminate panel can effectively predict the pedestrian head injury and deformation
pattern of the model. This method can be an appropriate tool for the vehicle, pedestrian safety evaluation and related
