Optimization of a B-Pillar Undergoing Roof Crush Using HEEDS COMPOSE

This paper demonstrates how to optimize the A-pillar, B-pillar, roof rail, rocker, front header, and roof bow components of a car for roof crush, utilizing ultra-high-strength steel. In addition to the gauge of the individual structural components, a soft zone trigger and its location within the B-pillar are introduced as design variables. LS-DYNA is utilized as the simulation tool with the COMPOSE (COMPonent Optimization in a System Environment) module for HEEDS MDO used to perform the optimization.
