| Abstract: | The fatigue life of a two-stage turbine disk transmission arm pin hole was predicted by the models of uniaxial,Von Mises strain and critical plane.A full-scale two-stage turbine disk was fabricated and debugged,and then tested for LCF(low cycle fatigue).The predicted life was compared with the life evaluated by fatigue test of real turbine disk,and the result shows that the predicted errors of the critical plane model are less than those of the uniaxial model and the Von Mises strain model,especially the error of SWT(Smith-Watson-Topper)model is 9.26%. |
| Keywords: | turbine disk multiaxial low cycle fatigue critical plane life prediction SWT(Smith-Watson-Topper) model Von Mises strain model |
