| Abstract: | Aiming at the LP rotor of a 600MW steam turbine, vibration and torsional vibration fatigue properties of the pre-wear and post-repair shafting are analyzed. Results show that vibration characteristic parameters of the post- repair shafting are in accordance with the original design and can meet the design specification, the unit fatigue strength is smaller than allowable material strength, which can ensure safe and stable operation. |
