Increasing the operating reliability of steam-turbine rotors

Assessment of fatigue damage in steam turbine shafting due to torsional vibrations

“…As applied to turbine rotors of thermal stations, these factors include a load ratio [6], high temperature [7], scale factor [8,9], stress concentration [9], nonuniformity of mechanical properties of steal in the rotor volume [10,11], etc. They should be allowed for, in order to achieve a reliable assessment of cyclic damage in a turbine shafting under vibration conditions.…”
