Numerical Analysis of Light Commercial Vehicle Headlamp for Pedestrian Safety

Abstract

New regulations about pedestrian safety entail the automobile producers to improve headlamp designs by reducing the pedestrian injury
during the event of car headlamp-pedestrian crash. In this study, a lightweight commercial vehicle headlamp was modeled with finite
element method and simulated under pedestrian impact. This work aims to predict the behavior of headlamp during the pedestrian crashes.
Initially, Finite Element Analysis of a sample headlamp model and regular pedestrian impactors were prepared. Then, static, modal and
Dynamic/Explicit analyzes were executed, respectively. The results show that the current model of headlamp was matched with the new
pedestrian protections regulations of EEVC/WG17.
