The vibration spectrum is an excellent tool for detecting and diagnosing faults in rotating machinery. But in truth it only tells half the picture. The time waveform and phase readings complete the picture, and it is essential that all vibration analysts understand how to correctly measure and interpret this data.

This presentation describes a series of fault conditions that can only be accurately diagnosed with time waveform analysis and/or phase analysis. We explore how to ensure that the time waveform is measured correctly so that useful information can be revealed – this is the place where most analysts make mistakes. We’ll present real-world case study examples where time waveform analysis reveals a new world for the analyst in terms of detectability, analysis and diagnostics. We then go on to demonstrate how easy phase readings can be measured with a single-channel analyser, a two channel-analyser, and a strobe. We then move on to describing a series of fault conditions that can be diagnosed and confirmed with phase analysis techniques. Finally, we look at how traditional VA phase techniques can be enhanced by conducting more detailed measurements (via Operating Deflect Shape and Motion Amplification) that allows us to truly visualize how the machine/structure/system is moving, thereby providing visual evidence for root cause analysis of machine failure modes.

This workshop is for all levels of experience regardless of skill set and is presented utilising 3D animations, software simulators and visual aids that will make it understandable to all.

Stuart has worked in the Condition Monitoring and Reliability sector for the last 23 years. He started his career working for Dupont as a Mechanical and Production Technician after completing a four year apprenticeship. It was here he was introduced to Condition Based Monitoring and setup a successful program at one of DuPont’s UK sites. He utilized technology’s such as Vibration analysis, Oil Analysis and IR Thermography moving the site from a time based maintenance strategy to a predictive and proactive one.  Stuart then worked for a Reliability Consultant company for a number of years implementing and running a number of other successful CBM programs across the UK.
In 1999, Stuart setup Reliability Maintenance Solutions Ltd with his colleague Dean Whittle. Together they have successfully grown the company over the last 20 years. RMS provides reliability consultancy, training, service, and products to a number blue chip companies across the UK, Europe and Middle East. Stuart has worked in many industry sectors including Oil & Gas, Petrochemical, Power and Paper. He is currently working on projects introducing and implementing the new Motion Amplification Technology within RMS and across a wide range of Industries at home and abroad.
