Optimal design of light commercial vehicle headlamp for pedestrian protection

Abstract

In this study, the headlamp of a light commercial vehicle was optimized in the way of pedestrian safety. This work aims to prevent harms to pedestrians in the urban crashes. Finite element analysis models of current headlamp and impactors representing pedestrian body forms were created. Static, modal and dynamic/explicit analyses were carried out by using existing and optimized headlamp models. Both models were in the simulations under the same boundary conditions. The results of two conditions were compared with each other. The results showed that connection regions of the headlamp have a major effect on pedestrian safety in pedestrian-vehicle collisions.
