Low Cycle Fatigue Life Prediction of Steam Turbine Rotor based on a New CDM Model

摘要：

　　Low cycle fatigue life of a steam turbine rotor is predicted using a new CDM model.A simulation experiment is made to compute the damage accumulation of a 300MW steam turbine rotor under cold start.Adopting the cyclic stress-strain relation,this new continuum damage mechanics model exhibits a conservative character.Comparison with result of the linear accumulation theory and practical test data indicates that present new nonlinear CDM model describes the damage accumulation more precisely and reasonably in engineering.
