The prototype of Hanhwa AUV (Autonomous Underwater Vehicle) was developed to prepare future system developments in Hanwha Corporation. This paper presents the procedure and results of the structural design and analysis for the End Cap of Hanwha AUV. Several methodologies used for structural optimization were presented and applied to the design of the End Cap structure. Both shape optimization and thickness optimization were performed simultaneously. And because the FEM analysis model was used for structural optimization, design and analysis procedures were simultaneously conducted. Several analysis methods such as static analysis, buckling analysis, and normal mode analysis were used with procedure that was similar to the MDO (Multidisciplinary Design Optimization). The objective is to design the structural weight. The constraints are maximum displacement and maximum von Mises stress in static analysis, the buckling coefficient in buckling analysis, and lowest natural frequency in normal mode analysis. The design variable concerning thickness optimization is the thickness of the End Cap shell, as well as the depth of the End Cap concerning shape optimization. In thickness optimization, the optimization for variable thicknesses at the final shape iteration was performed, and we can see that the weight was significantly reduced.
