| Abstract: | A finite element model of BIW is established. The torsional stiffness and modes are calculated using MSC Nastran. Based on the results of these, the optimization analysis and sensitivity analysis that the design variables are the thickness of parts are carried out. The target of optimization is to minimize the weight of BIW on condition of satisfying the requirement for torsional stiffness. By those analyses, improvement is made to meet the design requirements. |
