The book "Dynamics and Vibration of Rotating Shafts", written by Abbas Rahi, assistant professor of the Faculty of Mechanical and Energy Engineering of Shahid Beheshti University (SBU), Masoud Nourimotlagh, a master's graduate; and Mahmoud Mazare and Ehsan Davoodi, PhD graduates of the Faculty of Mechanical and Energy Engineering of SBU, has been published recently by SBU Press in 284 pages.
The book discusses dynamic modeling and vibration analysis of rotating shafts and covers various areas of vibration of rotating shafts. Since the prerequisite for the analysis of the frequencies and vibration modes of rotating shafts is their dynamic modeling, the vibration modeling of these shafts in transverse, longitudinal and torsional directions is described in this book, and after introducing the concept of coupling, models are presented in which the coupling between vibration modes is also considered. Considering the importance of transverse vibration in rotating shafts, dynamic-vibration modeling has a significant contribution in the book, and various well-known models of one to several degrees of freedom (such as Rankine, simple and extended Jeffcott, etc.) have been discussed. Also, regarding the effect of cracks on the critical speeds and vibration modes of rotating shafts, conventional methods for modeling and vibration analysis of cracked shafts have been introduced and the authors have attempted to express the effect of the crack parameters such as depth, length, inclination or transverseness on the vibration of rotating shafts.
Critical speeds are also one of the most important topics of vibration of rotating shafts. It includes sub-areas such as limping, backward and forward limping, main motion modes, Campbell diagram, and various factors affecting the value of critical speed. In addition, the types of misalignment, the effect of misalignment on the vibration of rotating shafts and the permissible limits of misalignment of couplings are among the other topics discussed in the book.
The book is useful for students of mechanical engineering, power plant engineering, railway machinery engineering, aerospace engineering, automobile engineering and other related fields. In addition to postgraduate students, this book is useful for engineers and activists working in various fields of industries, including power plants, compressors, turbines, automobiles, railways and aerospace.
