描述.Cracks can develop in rotating shafts and can propagate to relevant depths without affecting consistently the normal operating conditions of the shaft. In order to avoid catastrophic failures, accurate vibration analyses have to be performed for crack detection. The identification of the crack location and depth is possible by means of a model based diagnostic approach, provided that the model of the crack and the model of the cracked shaft dynamical behavior are accurate and reliable...This monograph shows the typical dynamical behavior of cracked shafts and presents tests for detecting cracks. The book describes how to model cracks, how to simulate the dynamical behavior of cracked shaft, and compares the corresponding numerical with experimental results. All effects of cracks on the vibrations of rotating shafts are analyzed, and some results of a numerical sensitivity analysis of the vibrations to the presence and severity of the crack are shown. Finally the book describes some crack identification procedures and shows some results in model based crack identification in position and depth. ..The book is useful for higher university courses in mechanical and energetic engineeri

Cracks in Rotating Shafts,pagate from some small imperfections on the surface of the body or inside of the material and it is most likely to appear in correspondence of high stress concentration. For example, figure 1.1 shows a crack developed in the stiffening plate of a generator casing.

Typical Dynamic Behaviour of Cracked Shafts,tion monitoring system is installed and vibrations are analyzed. This chapter is focused on the typical symptoms that can be noticed in industrial rotating machinery and specifically three aspects are considered: the vibrations at rated speed, the so-called . that affects cracked rotors and the vibrations during speed transients.

Results Obtained Using Simulations,ated results are obtained with the approach described in sections 5.3.1 and 5.4.3. The good agreement between the results confirm the validity of the described approach. Other simulated results will be presented also in chapter 7 of this book, in order to highlight different peculiar behaviours.
