Research on FE Modeling Common Method and Integration System for Nuclear Power Valve

Because of the high security, shape complexity of valve cavity and the nonlinear of joint surface at sealing position, establishing the finite element model quickly and accurately that could meet engineering accuracy and calculation condition is the problem that need urgently solved. A new method on knowledge reuse process of finite element analysis among valve similar model is presented based on modular thought, which could effectively improve the simulation accuracy and efficiency. Evaluation index system would be constructed according to the characteristics of nuclear power valves in order to perfect the technical standard and the norm of nuclear power valve design in our country. And on these bases above, the integrated platform as practical engineering tools could be constructed, which integrates design, simulation, and optimization of nuclear power valves together supporting heterogeneous model transfer. It is expected to give theoretical development and practical application to improve the design ability and the product performance of nuclear power valves.
