OVERVIEW

A practical course in the fundamentals of machinery diagnostics foranyone who works with rotating machinery, from operator to manager,from design engineer to machinery diagnostician.

This comprehensive book thoroughly explains and demystifiesimportant concepts needed for effective machinery malfunctiondiagnosis:

(A) Vibration fundamentals: vibration, phase, and vibrationvectors.

(B) Data plots: timebase, average shaft centerline, polar, Bode,APHT, spectrum, trend XY, and the orbit.

(C) Rotor dynamics: the rotor model, dynamic stiffness, modes ofvibration, anisotropic (asymmetric) stiffness, stability analysis,torsional and axial vibration, and basic balancing.

Modern root locus methods (pioneered by Walter R. Evans) are usedthroughout this book.

(D) Malfunctions: unbalance, rotor bow, high radial loads,misalignment, rub and looseness, fluid-induced instability, andshaft cracks.

Hundreds of full-color illustrations explain key concepts, andseveral detailed case studies show how these concepts were used tosolve real machinery problems.

A comprehensive glossary of diagnostic terms is included.
