This book was released on 1965 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This design handbook presents data and methods for use in analyzing the dynamical performance of a rotor supported in fluid film type bearings. The data are given in form of design charts covering: (1) The dynamic bearing coefficients; (2) The onset of hydrodynamic instability; and (3) The critical speeds and the unbalance response of a simple rotor-bearing system. The design charts are in dimensionless form and cover a wide range of bearing geometries and operating conditions. Several different types of fluid film bearings are considered together with various forms of lubrication.

Available in PDF, EPUB and Kindle. Book excerpt: This Part IV of the Final Report presents design data for the stiffness characteristics of ball bearings for use in analyzing the dynamical performance of a rotor. The dynamic characteristics of fluid film bearings are given in Part III which also gives the methods for performing the analysis of the rotor-bearing system. Design data are presented for the extra-light and light group of deep-grooved and angular contact bearings undergoing either a pure radial load, pure axial load, or combined radial load with axial preload. The data are given in graphical form and cover both radial stiffness and load- carrying capacity. A nominal damping value for ball bearings, obtained from experimentation, is suggested. Some of the general guide rules for the selection of ball bearings are given. These are concerned with fatigue life, limiting speeds, design, and lubrication. Safe load levels are indicated.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes a computerized data storage retrieval system for the static and dynamic characteristics of fluid film bearings. The procedure combines asymptotic power law extrapolation outside the stored data range with smooth interpolation within the data table. Thirty-one data tables have been prepared and installed in the system. The procedure allows addition of new data tables in the future. The retrieval software allows the user to list the data content in either the dimensional or the dimensionless form or to generate data lines in the sequence and format directly usable as input to the rotordynamics software described. Inertia, compliance and damping effects of the pedestal can be included in the retrieval dynamic characteristics of each bearing.

Download or read book Rotor Systems written by Rajiv Tiwari and published by CRC Press. This book was released on 2017-11-22 with total page 1092 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to give a basic understanding of rotor dynamics phenomena with the help of simple rotor models and subsequently, the modern analysis methods for real life rotor systems. This background will be helpful in the identification of rotor-bearing system parameters and its use in futuristic model-based condition monitoring and, fault diagnostics and prognostics. The book starts with introductory material for finite element methods and moves to linear and non-linear vibrations, continuous systems, vibration measurement techniques, signal processing and error analysis, general identification techniques in engineering systems, and MATLAB analysis of simple rotors. Key Features: • Covers both transfer matrix methods (TMM) and finite element methods (FEM) • Discusses transverse and torsional vibrations • Includes worked examples with simplicity of mathematical background and a modern numerical method approach • Explores the concepts of instability analysis and dynamic balancing • Provides a basic understanding of rotor dynamics phenomena with the help of simple rotor models including modern analysis methods for real life rotor systems.
Download or read book Analytical Methods in Rotor Dynamics written by Andrew D. Dimarogonas and published by Springer Science & Business Media. This book was released on 2013-02-19 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and construction of rotating machinery operating at supercritical speeds was, in the 1920s, an event of revolutionary importance for the then new branch of dynamics known as rotor dynamics. In the 1960s, another revolution occurred: In less than a decade, imposed by operational and economic needs, an increase in the power of turbomachinery by one order of magnitude took place. Dynamic analysis of complex rotor forms became a necessity, while the importance of approximate methods for dynamic analysis was stressed. Finally, the emergence of fracture mechanics, as a new branch of applied mechanics, provided analytical tools to investigate crack influence on the dynamic behavior of rotors. The scope of this book is based on all these developments. No topics related to the well-known classical problems are included, rather the book deals exclusively with modern high-power turbomachinery.

Available in PDF, EPUB and Kindle. Book excerpt: Thermohydrodynamic Instability in Fluid-Film Bearings aims to establish instability criteria for a rotor-bearing system associated with fluid-film journal bearings. It focuses on how the influencing factors such as rotor flexibility, manufacturing imperfections such as residual shaft unbalance, and service-related imperfections such as uneven wear affect the stability of a rotor-bearing system It shows how the specific operating conditions such as oil inlet temperature, inlet pressure, and inlet position of a rotor-bearing system directly influence the system stability General design guidelines have been summarized to guide the engineering system design and the correction of failure and/or malfunction
