基于UG的透平叶片坯料快速设计系统OA

Aiming at the problems of a wide variety of turbine blade blanks,complex shapes and difficult model modification,a template-based blade blank parametric modeling system is designed by using UG 12.0 secondary development tools and Visual Studio 2015 programming software.On the basis of studying the existing parametric design,the dimensional data of different types of blade blanks are stored in Excel,and a reusable library of turbine blade blank models is established.The example proves that the system can easily and quickly obtain the blade blank model and two-dimensional engineering drawing required by the designer by modifying the model parameters of the blade blank according to the actual needs of the project,which shortens the design and devel-opment cycle of the turbine blade forging blank.The design of the reusable library improves the efficiency of engineers in the enter-prise to call and check the required blade blanks,and reduces the probability of errors.
