ABSTRACT:
The paper calculated the temperature and stress fields
of 1000 MW ultra-supercritical steam turbine rotors which start in cold
condition using the finite element calculation program (ANSYS). After
getting rotor stress field, the paper use the general slope method to estimate
the low cycle fatigue life loss, the rest of the conditions can be calculated
in this method.
