Development of Parametric Modeling System for the Whole High Bypass Ratio Turbofan Engine based on Secondary Development of UG

Abstract

In this paper, the method of developing parametric design system based upon UG with VB (Visual Basic) and Microsoft Excel has been studied. The development strategy and implement method of the parametric modeling system for the whole high bypass ratio turbofan engine based on secondary development of UG have been put forward. The parametric modeling system for the whole high bypass ratio turbofan engine has been developed, and the parametric solid model of the whole high bypass ratio turbofan engine can be established rapidly with this system. The design period of the high bypass ratio turbofan engine was shortened, the design efficiency was heightened, and the design quantity was improved obviously. The system structure and some program codes were presented in the paper. The method presented in this paper has reference value to developing the parametric design system of complex products.
