Straightening Process Modelling of Steam Turbine Rotors Applying Tension Relaxation Method
Procedure of straightening rotors bending is complex, but it is possible to optimise it by applying the appropriate model. Application of the finite elements method at the example of straightening of the rotor for turbine TK 200-130 LMZ in power plant Tuzla. Applied method was tested by comparison with results obtained “in situ” and has shown satisfactory results. Acquired knowledge may be used in straightening of rotors and other machine parts, as well as for further research in modelling of elastic-plastic deformations.
