Numerical study of a hybrid wire-net bonnet for pedestrian safety

In the automotive field the attention of public opinion is focused on the safety of vulnerable road users (VRU) pedestrians and cyclists. At the same time the reduction of pollutant emissions is very important. To improve these two aspects of the automotive design, the use of non-conventional materials and innovative design solutions is increasingly important. In this perspective a new wire net design for the inner structure of a bonnet is proposed and developed in this work. The influence of the main design parameters (thicknesses, materials) is investigated.
