Part 1 Basic concepts and theory: magnitude - units of measurement; frequency content; time waveform; measurement of vibration - introduction, transducers, signal conditioning; criteria - externally measured vibration in general machinery/gearboxes/rolling contact bearings/reciprocating machinery, shaft vibration relative to the bearing housing; summary of techniques. Part 2 Practical issues: selecting the right parameter; problems in simple usage (portable monitoring with vibration meter or data collector); repeatibility (portable monitoring) - non-repeatability due to machine condition or measuring technique; experience with permanent monitors; implementation of permanent monitors. Part 3 Equipment and instrumentation: portable meters and analysers - vibration meters for general use, portable frequency analysers; portable data collectors/analyzers - essential features, the exception report, advantages of the data collector system, data collectors/software features available, desirable features, data logger suitable for monitoring rolling contact bearings using the shock pulse method; permanent monitors/on-line data acquisition and analysis equipment - description of a permanent monitor, protection monitors, interfaces with on-line data acquistion and analysis equipment; on-line continuous monitoring. Part 4 Applications and case studies: applications - specific industries and machines where certain techniques are most appropriate and most often used, choosing whether to use simple portable monitoring/data collectors/permanent on-line monitors, when to use external vibration measurements and when to use relative shaft vibration; case studies - user of frequency analysis etc (large fan), (food oven fans), use of time averaging techniques (helicopter gearboxes), use of shock pulse monitoring (bearings), use of the envelope technique (nuclear reprocessing), (paper machinery), shaft orbit (high pressure turbine), transients (centrifugal compressor) (power station turbo-generator), amplitude and phase of vibration (centrifugal blower). Part 5 Buyer's guide: companies; products; services.
