Enhancing the Crashworthiness of Passenger Vehicle through Modification of Bumper Beam Design and Energy Absorption Materials

Abstract

The majority of injuries and deaths are caused by a vehicle accident in the front structure. This research endeavours to systematically refine bumper beam structures through an amalgamation of computational simulations, advanced material selection, and experimental validations. A multifaceted approach is employed, encompassing finite element analysis (FEA) techniques to model and predict crash responses, coupled with iterative design iterations to optimize energy absorption and deformation characteristics. The study delves into the synergistic effects of material properties, geometric parameters, and structural arrangements on crash performance. The results underscore the intricate interplay between structural rigidity, energy absorption, and occupant safety. This work entails designing a car bumper beam in the W section that could withstand a low-impact collision with a new energy absorbing material. The optimized designs exhibit superior crashworthiness metrics, highlighting the potential to significantly mitigate collision-induced forces. This study underscores the imperative for continuous exploration and innovation in bumper beam design to elevate vehicular safety standards and ultimately reduce the human and economic toll of road accident.
