| Abstract: | The complex centrifugal forces caused by the irr egular blade and thirty-three kinds of dismatch cases occuring in the rabbet of the turbo simulating the machining error and accumulating deformation are consi dered to study the stress distribution in the rabbet by means of elasto-plastic contact FEM. Some useful results are obtained which are useful to avoid making dangerous turbo and to design new kinds of rabbet which can reduce the stress l evel of the turbo obviously. |
