Fatigue Damage Research on Rod-Fastening Rotor of Gas Turbine Considering Start-Up Stage

Abstract:

Fatigue damage was analyzed of the rod-fastening rotor of gas turbine in the process of frequent start-up. The maximum stress of rotor was calculated, applying nonlinear damage mechanics model to analyze the fatigue damage of the rotor in the process of startup. Finally, we get the damage quantity in each process of start. It provides certain theoretical basis on slowing degradation velocity of the rotor.
