| Abstract: | Based on personal computer, a FDM/FEM integrated analysis system of thermal stresses was developed, and 3D numerical simulaion of thermal stresses in large castings during solidification has been carried out. The residual stress fields in the blower case castings with different technological processes were analyzed and the tendency of hot tearing in the main shaft of water turbine was predicted. |
