Abstract

The paper presents the results of fatigue life analysis of the steam turbine last stage damaged blade. Damages to the shape of circular side cut of the airfoil at the three different positions along airfoil are considered. For each type of blade damage, an additional vibration analysis with the influence of centrifugal force is conducted and the results are presented in the form of mode shapes and Campbell diagrams.

Keywords

fatigue life estimation; vibration calculation; Campbell diagram
