압력용기 매니폴드 밸브의 구조최적설계

다국어 초록 (Multilingual Abstract)

This study proposes the structural optimization of a manifold valve. FE analysis is performed to evaluate the strength of a manifold valve. In addition, the structural optimization technique is applied to reduce its weight. In this study, the optimization method using the kriging interpolation method is adopted to obtain the minimum weight satisfying the strength constraint. The maximum stress and the weight are replaced by the metamodels. In this process, the sample points are generated by latin-hypercube design. Optimum designs are obtained by ANSYS Workbench and the in -house program.
