Due to positive feedback from our previous 5 case studies series this is our bonus case study brought to you with the Reliability Training Institute. If you have missed any of the previous case studies, they can be found on my LinkedIn profile, Seasoned Analyst blog and on the RMS Website.
Please like, follow, and share for more content.
This case study is a lot longer at over 34 minutes. Here we cover a 2-year project period from initial root cause diagnosis to designing, trialling, and implementing an innovative cost-effective solution.
A profitable plant is reliable, safe and a cost-effectively maintained plant.

CBM Conference 2019 UK
I presented at my first Conference, and it was the first CBM Conference in the UK. It was well worth attending as I got to discuss various challenges in the condition monitoring and reliability sector, and the most common discussion point was buying from senior management and how to continually highlight the benefits of a condition monitoring program.
In addition there were vendors there demonstrating the latest advancements in condition motioning technology from vibration online and walk around, thermal imaging safety, ultrasound new high sampling rates time waveform analysis to motor electrical condition monitoring.
Dynamic Absorbers are often overlooked and not used, they can be seen as a band aid or a last option for some vibration problems. Whereas in some cases they can be the only cost efficient option, and they are very effective.
The Vibration Dynamic Absorber is a unique bespoke item, maintenance free, that is designed to absorb unwanted energy.
It is tuned to have the same resonant frequency as the structure to set up an out of phase signal reducing the signal generated by the structure.
Knowing the forcing frequency of interest, the material dimensions and parameters including Density (S.I. Units), Young’s Modulus (S.I. Units) and Area Moment of Inertia (si) we can design a component that is tuned to the problem frequency.
