A parametric lightweight turbine disk structure CAD/CAE integration method

The relevance between input parameters and the files of parametric computer aided design (CAD)/computer aided engineering (CAE) integration was analyzed based on the lightweight turbine disk structure's characteristics. C/C++ program was compiled, and software UG/OPEN API was used to accomplish parametric modeling. CAE softwares were called sequentially to run the scripts modified based on one-way fluid structure interaction method to insure the relevance between input parameters and relevant files. Thus, the automated integration of parametric lightweight turbine disk CAD/CAE process was achieved. The program running results show that compared with the manual work which is the same with CAD/CAE process, this method costs less than 54 min, proving that the design and analysis efficiency is improved effectively.
