Research on CAD/CAE/MDO integrated system for nuclear valve products

In order to realize rapid response to performance-driven design for nuclear valve products, a rapid design platform is constructed by combining the structural features with the multi-characteristic optimization requirement, which integrates parametric design, multi-characteristic simulation, and multidisciplinary design optimization of nuclear power valves together. Through the integration of heterogeneous CAX/MDO software, such as UG, ANSYS and iSIGHT, the analytical efficiency is enhanced by coupling respective and unique advantage of various software systems, and the mutual coordination and information sharing are realized between the heterogeneous systems. The application example shows that the system is convenient operation that improves the automation in design and analysis on nuclear valves. The results can provide a practical and effective development method and technical reference of the integrated design system for valve products.
