Abstract

Chapter 8 deals with the inverse problem of the one encountered in Chap. 5, e.g. the heat generated by torsional vibration of rotating shafts. The corresponding mechanisms are associated with internal damping and plastic deformation. Practically all the energy of 476 plastic deformation is transformed into heat. For elastic deformation part of the strain energy is transformed into heat, depending on material loss factor. This phenomenon has been identified as the cause of large-scale failures of power equipment, with electrical disturbances being the cause of rotor torsional vibration. Maximum temperatures given in the form of design nomograms can assist in estimating the overheating of shaft of rotating machinery, where such phenomena are present. A typical turbo-generator shaft is analyzed for vibrations occurring during electrical transients.
