| Abstract: | In this paper, with the real curve of turbine start-up and stop processes being applied, a three dimension instantaneous temperature field and non-linear stress field analysis of 600MW turbine is given .Further more ,the rotor fatigue lives of the start-up and stop processes are calculated with the low-cyclic fatigue life curve being applied. In the analysis of the temperature and stress field, the axis-symmetry finite element method is employed. |
