Development of a method for multidisciplinary parametric optimization of vehicle hood reinforcement

Abstract

The goal of this paper is to develop and test a multidisciplinary optimization technique for designing structures that are subjected to both static and dynamic loads, using the digital twin of a vehicle hood as an example. This method reduces the weight of the hood reinforcement and increases the probability of pedestrian survival when hitting the head. This is due to the implementation of technological and layout constraints, as well as the requirements for stiffness, frequency characteristics and hood denting.
