Aiming at the problem of long cycle and high cost in designing power valve products at present, a nuclear power valve design method for collaborative design, simulation and optimization is put forward. Through the summarized characteristics of nuclear power valve products in CAE series, the basic framework of parametric CAE analysis is constructed. Combined with parametric variant design and simplification module for valve parts, the heterogeneous information between CAD and FEA of valve models is expressed by using the universal data exchange technology. According to the integrated development framework, an integrated system, which integrates parametric design, multi-characteristic simulation, and multidisciplinary design optimization for the nuclear power valves together supporting heterogeneous model transfer, is constructed and validated through a case. Through integration of heterogeneous CAD/CAE software such as UG, ANSYS and iSIGHT, the analytical efficiency is enhanced by coupling respective and unique advantage of various software systems. This transfer is benefit for mutual coordination and information sharing that improves the automation in design and analysis on the valve products.
