ASSESSMENT OF FATIGUE DAMAGE IN STEAM TURBINE SHAFTING DUE TO TORSIONAL VIBRATIONS

摘要

We present a technique and results of fatigue damage evaluation of steam turbine shafting material under conditions of torque vibrations occurring at turbogenerator abnormal modes of operation (short circuit, random paralleling start, etc.). Combinations of loading parameters, which provide the shafting limiting conditions, are identified.
