An automated design system of an airbag is presented, which autonomously correlates airbag finite element simulation and the optimization process. Current airbag correlation is achieved through the manual application of trial-and-error procedures implemented by skilled engineers. The developed system successfully correlates a baseline model automatically and reduces the time and skill required for correlation and increase repeatability. The thin plate is indented during the manufacturing process such as tensile process, welding process, and painting process. This deflection causes the mismatch between pad and frame on side panel, uneven surface and pre-stress in the manufacturing process. This study presents the optimized manufacturing process to prevent the deflection of side panel based on the metamodeling with ABAQUS. Effective parameters which are major factors of the deflection are selected through parametric study. The optimum conditions of selected effective parameters to minimize the deflection are presented. We adopt metamodel from the simulation results for the optimization. Also, we finally suggest the optimized condition of manufacturing process for bus side panel to prevent the deflection with the selected effective parameters.
