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.
