This reference is a powerful tool to strengthen vital in-house competency on the subject for professionals in a variety of fields. After presenting governing fundamental principles and background on modern measurement, computational tools, and troubleshooting methods, the author provides practical instruction and demonstration on how to diagnose vibration problems and formulate solutions. The topic is covered in four sequential sections: Primer on Rotor Vibration, Use of Rotor Dynamic Analyses, Monitoring and Diagnostics, and Troubleshooting Case Studies. This book includes comprehensive descriptions of vibration symptoms for rotor unbalance, dynamic instability, rotor-stator rubs, misalignment, loose parts, cracked shafts, and rub-induced thermal bows. It is an essential reference for mechanical, chemical, design, manufacturing, materials, aerospace, and reliability engineers. It is particularly useful as a reference for specialists in vibration, rotating machinery, and turbomachinery.

Diagnosis and correction are critical tasks for the vibrations engineer. Many causes of rotor vibration are so subtle and pervasive that excessive vibration continues to occur despite the use of usually effective design practices and methods of avoidance.Rotating Machinery Vibration: From Analysis to Troubleshooting provides a comprehensive, consolidated overview of the fundamentals of rotating machinery vibration and addresses computer model building, sources and types of vibration, and machine vibration signal analysis. This reference is a powerful tool to strengthen vital in-house competency on the subject for professionals in a variety of fields.
This book includes comprehensive descriptions of vibration symptoms for rotor unbalance, dynamic instability, rotor-stator rubs, misalignment, loose parts, cracked shafts, and rub-induced thermal bows. It is an essential reference for mechanical, chemical, design, manufacturing, materials, aerospace, and reliability engineers. Particularly useful as a reference for specialists in vibration, rotating machinery, and turbomachinery, it also makes an ideal text for upper-level undergraduate and graduate students in these disciplines.

Dr. Adams worked on rotating machinery engineering for 14 years in industry prior to becoming a professor in 1977, including employment at Allis Chalmers, Worthington, Franklin Institute Research Laboratories, and Westinghouse Corporate R&D Center.
Vibration analysis is a process of looking for anomalies and monitoring change from the established vibration signature of a system. The vibration of any object in motion is characterized by variations of amplitude, intensity, and frequency. These vibration signatures can be correlated to physical phenomena, making it possible to use vibration data to gain insights into the health of equipment. Vibration analysis can be used to:
Vibration analysis can be used to determine whether bearings have been properly installed. In a taper bearing, for example, the inner race has to be expanded to take up the clearance between the rotating element and the outer race. If that clearance is not removed, the bearing may wind up crooked or wobbling. This will introduce non-periodic features into the vibration signal. Phase analysis also can be used to check bearing concentricity.
Vibration analysis also can be used to determine how well a machine is assembled. It can detect misalignment in a pump, for example, determining whether the rotating elements are binding, if the base is uneven, or if torsion exists between motor and pump.
The rotating equipment vibration analysis training PowerPoint set has 627 slides with detailed content on machinery vibration analysis, bearing vibration condition monitoring, industrial equipment vibration data collection, and measurement of vibration.
Included are full details explaining vibration data collection, vibration measurement, vibration analysis, and machine vibration fault diagnosis. This set of equipment and machinery vibration training PowerPoint and course materials collect together the expert advice and knowledge that vibration analysis expert Peter Brown has gained from more than 40 years of machine vibration measurement and vibration analysis experience.
Accompanying the Fundamentals of Machinery and Equipment Vibration PowerPoint presentation materials are 17 Word documents and white papers on rotating equipment vibration analysis and equipment vibration fault finding. Including articles used to supplement various of the seminar topics and provide a thorough explanation of key issues about bearing vibration condition monitoring, industrial equipment vibration data collection, and the measurement of vibration.
You get the original MS PowerPoint 2003 presentation slides containing a mixture of text, graphics and images. The full course content covers important aspects of equipment vibration measurement, rotating machinery vibration analysis, equipment condition monitoring, and machine fault correction.
The Rotate software package is part of the m+p Analyzer Software for noise & vibration measurements and analysis. It provides a wide range of data acquisition and analysis tools for capturing and understanding noise and vibration induced in rotating and reciprocating machines by their motion. Fixed and variable speed machines are accommodated as are both structural vibration and condition monitoring diagnostics. Multiple tacho inputs can be processed for accurate speed tracking during analysis. Spectral mapping, order tracking, time history and orbit data analysis are all available.
With the m+p Analyzer Rotate software, the acquisition of spectra for an online waterfall display can be triggered based on RPM or time values, and orders can also be acquired and displayed online. The simultaneous acquisition of vibration and tacho signals as time records (throughput recording) additionally allows offline postprocessing analysis with spectral maps and advanced computed order tracking. The software uses intelligent wizards that, step by step, guide through the process of performing a rotating machinery data acquisition and analysis. Waterfall and 2D graphs can be directly copied and pasted into ActiveX compliant applications such as Microsoft Word or PowerPoint. 041b061a72
