| Abstract: | The non-convergence problem for calculating the burst speed of disks with small load by using the analytical large deformation method has been found and solved in this paper, therefore the analytical large deformation method has been consummated. Using this method and the finite element method, the author has calculated the burst and the yield speed of the high pressure disk in counter-rotating turbine, and the calculating accuracy of the two methods has also been examined by selecting the experimental datum of the model disks. Furthermore, the two methods have been applied in calculating the burst and the yield speed of the eccentric disk. |
