Parametric Design of Three-Eccentric Butterfly Valve Based on CAD/CAE Integrated

Taken main geometry parameters of butterfly valve,three dimensional parametric models of valve parts are automatically created in Solidworks by VBA programming.FEM model is obtained by importing the geometry model into FEM environment,and then the CAD/CAE integration is realized.FEM calculation shows that parametric model can be used in fast model creation with different sizes,and it makes digital design and scheme optimization possible.
