Designers and operators of rotating machinery have to deal with the effects of machine vibration and wear. The increasing demands for quieter machine operation, longer machine life and a greater efficiency of operation have led to the use of sophisticated design aids. Research into rotating machinery is therefore of substantial and increasing importance. Rotordynamics '92 provides a record of some of the most recent research methods and results relating to the design and operation of rotating machinery. The conference is international in character and draws on research from a wide range of respected sources.

This book deals with rotordynamics of automotive turbochargers while encompassing the analysis of the dynamics of rotating machines at very high rotor speeds of 300,000 rpm and above. This interdisciplinary field involves 1. thermodynamics and turbo-matching knowledge to compute working conditions of turbochargers, 2. fluid and bearing dynamics to calculate various operating thrust loads and to design the rotating floating ring bearings (two-oil-film bearings), and 3. tribology to improve the rotor stability and to reduce the bearing friction. Mathematical background in modeling and simulation methods is necessary; however, the prerequisites have been kept to a minimum. The book addresses both practitioners working in the field of rotordynamics of automotive turbochargers and graduate students in mechanical engineering.

As the most important parts of rotating machinery, rotors are also the most prone to mechanical vibrations, which may lead to machine failure. Correction is only possible when proper and accurate diagnosis is obtained through understanding of rotor operation and all of the potential malfunctions that may occur. Mathematical modeling, in particular

This book discusses the technological developments achieved by distinguished figures in the history of mechanism and machine science (MMS). This is the fifth volume of a series of books which gathered contributions on the leading scientists in the field. This book focuses specifically on the IFToMM community and its activities over the last 50 years, showcases who-is-who in MMS, and emphasizes—together with the previous books of the series—the significance of MMS through time. Each chapter recognizes persons whose scientific work resulted in relevant technical developments in the historical evolution of MMS within IFToMM. Biographical notes describing the efforts and achievements of these persons are included as well, but a technical survey is the core of each chapter, offering a modern interpretation of their legacy.

The papers presented on this occasion examined the most significant aspects of diagnostic strategies, emphasizing the importance of predictive maintenance in reducing production shortages and the costs of plant management. The contributions of these authors allow a critical comparison of the varied experiences in developing and applying the different diagnostic methodologies employed in several parts of the world. The following problems are discussed: characteristics of condition monitoring systems - data acquisition techniques and data processing methodologies; choice of transducers and of measurement point locations; data compression techniques; alarm levels evaluation (acceptance regions); strategies for detecting malfunction conditions; diagnostic methodologies for the on-line and off-line identification of the cause of fault; expert systems; definition of the guidelines for the presentation in control rooms of monitoring data and diagnostic results; rotordynamic models used, off-line, to confirm faults diagnosed on-line.
