Abstract

Pedestrian head protection is mainly focused on energy absorption when impacting the bonnet. But the technical solutions for mitigating the impact are completely different for the head protection when impacting the windscreen.

Even if regulations do not require an assessment of the protection offered by the windscreen in case of pedestrian impacts, consumerism increased requirements incite us to study in-depth the windscreen, its shape, its boundary conditions and its bonding to optimise adult pedestrian head protection.

Large amount of physical tests were performed with varying all the parameters in order to assess the relative influence of each one.

In parallel, correlation modelling and prediction modelling were performed. Different meshing formulations were also investigated.

The results will be presented showing the effects on the different parameters and the difficulty of modelling them.

This study results in the release of new technical specifications for the windscreen that has to be compatible with the other mechanical and acoustical requirements that need to be fulfilled as well.
