Abstract

There is no doubt that the motorcycle helmet could protect the rider from head injuries during impact. However, besides the cranial impact, the facial impact could happen and the impact energy could cause fatal brain injuries too. The protection of facial injuries is as important as that of cranial injuries for motorcyclists. Among motorcycle helmets only the full face helmet has chin bar design to protect the rider from facial injuries. Hence, it is necessary to investigate the protective capability and the energy absorbing mechanism of chin bar during impact. The main objective of this study is to establish a three dimensional finite element helmet model with chin bar to perform dynamic analysis for facial impact. The analytical results were compared with the experimental outcomes to validate the finite element model. Different impact types were observed according to different standard testing methods. Material properties of chin bar were modified in the simulation to study the influence of chin bar stiffness during impact.
