Download or read book Dynamics of Rotors and Foundations written by Erwin Krämer and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rotordynamics are of great importance in the design, manufacture and assembly of turbomachines as well as in ensuring their safe operation. Also important are the dynamics of the foundation and its interaction with the dynamics of the rotor. This book is divided into four parts. Following a presentation of the basic theory the dynamics of rotors supported on several bearings. The third part describes the dynamics of foundations of turbine line-outs and the calculations for a turbomachine coupled with its foundation. The last part includes a section on estimation procedures, a comprehensive presentation of the theoryand practice of rotors having a transverse crack, a section on the mathematical fundamentals and a description of the computer program used for the examples in the book. The book addresses both the practical engineer and the theoretician and should provide manufacturers, operators, university and polytechnic lecturers and students with an understanding of the vibrations of turbomachines. The results are described in such a way that they can be easily understood and applied.

Available in PDF, EPUB and Kindle. Book excerpt: Stability analysis of high-speed machinery based on rigid rotor model mounted on rigid supports was found to be inadequate for stability predictions. But in actual practise bearings have some flexibility. Stiffness and damping properties of fluid film bearings alter the critical speeds of a rotor. Dynamic coefficients of fluid film bearing are dependent on speed, geometry of the bearing and other operating conditions. Plain circular bearings do not suit the stability requirements of high-speed machines and precision machine tools. Alternate bearing designs are sought to meet the new requirements. But a very little information is available in this field. In this work dynamic characteristics and stability of rotor-bearing system supported on circular and non-circular hydrodynamic bearings (short bearing and finite bearing) is studied. To demonstrate the worth of the study, it is proposed to take up models like bearings supporting rigid rotor and simplified flexible rotors for different bearing configurations. This study appears to provide a better understanding of this type of problem and the present results should be utmost importance to rotor-bearing system designers and analyst.

Download or read book Balancing of High Speed Machinery written by M. Darlow and published by Springer. This book was released on 1989 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern rotating machinery, particularly turbomachinery, is frequently being designed to operate at higher speeds than in the past. Consequently, there is an increased need to balance high-speed rotors. The purpose of this book is to provide the engineering student or practicing engineer with a single, complete reference on high-speed rotor balancing. To this end, a detailed analytical background and practical application procedures are presented for each of the principal high-speed rotor balancing methods, i.e. modal balancing, influence coefficient balancing and the Unified Balancing Approach. This information is supplemented and supported through a presentation of the theoretical development of synchronous rotor vibration and a brief overview of rigid rotor balancing techniques and machines. This is the first time this material is available in a single, concise volume, together with detailed descriptions of application procedures.

Available in PDF, EPUB and Kindle. Book excerpt: This text is intended for use as an advanced course in either rotordynamics or vibration at the graduate level. This text has mostly grown out of the research work in my laboratory and the lectures given to graduate students in the Mechanical Engineering Department, KAIST. The text contains a variety of topics not normally found in rotordynamics or vibration textbooks. The text emphasizes the analytical aspects and is thus quite different from conventional rotordynamics texts; potential readers are expected to have a firm background in elementary rotordynamics and vibration. In most previously published rotordynamics texts, the behavior of simple rotors has been of a primary concern, while more realistic, multi-degree-f-freedom or continuous systems are seldom treated in a rigorous way, mostly due to the difficulty of a mathematical treatment of such complicated systems. When one wanted to gain a deep insight into dynamic phenomena of complicated rotor systems, one has, in the past, either had to rely on computational techniques, such as the transfer matrix and finite element methods, or cautiously to extend ideas learned from simple rotors whose analytical solutions are readily available. The former methods are limited in the interpretation of results, since the calculations relate only to the simulated case, not to more general system behavior. Ideas learned from simple rotors can, fortunately, often be extended to many practical rotor systems, but there is of course no guarantee of their validity.
