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.
