Stiffness of axle mounting structure is one of basic factors affecting on ride & handling performance of the vehicle. The easiest way to increase stiffness of the structure is increasing thickness of sheet metal panels or adding reinforcement. But that means an increasement of mass and process in manufacturing. Design for six sigma (DFSS) is a practical technique for robust and optimized design in manufacturing industry. In this study we applied DFSS to optimize thickn ... 전체 초록 보기
