Modeling Using UG for Some Turbine Blade and Stress Analysis of Patran/Nastran FEM

Some turbine blade’s model of three dimensions was built using CAD software UG,and a method of building complex precise model was offered.Aiming at different phases of modeling such as line construction,surface building and surface finishing,some optional methods were offered.It still has reference value for readers of using other modeling softwares.The model that was built in UG was imported into Patran/Nastran FEM software to analyze its stress condition,and it made prepair for the coming life prediction.
