BIW structure development in accordance with passive safety requirements using several optimization methods

Abstract

The article is focused on the BIW characteristics and behavior optimization in terms of EURONCAP rules. Variable parameters: part’s shape, material, thickness. With multi-disciplinary, topological and topography optimization the most acceptable BIW behavior during virtual crash-tests has been achieved. All design improvements were implemented in accordance with stamping and assembly capabilities, restrictions on the use of each type of material. These requirements are especially important because updated design has been developed for the final stage and supposed to be frozen.
