Half-day (4-hour) interactive workshop
Exact time: 1:00PM to 5:00PM
Description:
Resonance is a condition that is often misdiagnosed and commonly goes undiagnosed, resulting in persistent high amplitude vibration issues for long periods of time. Structural resonance typically results in highly directional vibration and increased amplitudes that can be difficult to resolve without the proper engineering approach.
In 2023, Kyle led the workshop through an in depth acoustic resonance condition, and exploration of what solutions could be implemented. Building on this topic, this years workshop will discuss new examples of resonance, and introduce cost implications associated not only with damaging vibration, but how operating strategies can compound lifecycle costs.
This presentation will focus on methods for diagnosing resonance and technology available to develop effective solutions without resorting to costly trial-and-error methods. Material presented will be supplemented by a case study where a complex resonance problem was addressed for an end user in the refining industry. A multi-stage charging pump was exceeding alert levels at both the inboard and outboard bearing locations, with vibration amplitudes greatest in the vertical direction and a clear correlation with the time of the day. The inboard bearing housing vibration was much more directional than the outboard bearing housing vibration. Investigation revealed that both structural resonance and acoustic resonance were being excited, with the structural resonance limited to the inboard bearing housing and the acoustic resonance affected by fluid temperature. Our review of this case study will include a brief overview of resonance, methodology for field testing and diagnosis, and solution development and implementation.
