Imbalance, misalignment, rubs, rotor instability, and resonances on turbomachinery: what tools to capture, analyze and characterize those typical faults?
This webinar presents the main common issues that occur with turbomachinery and how to reach a relevant diagnostic. The discussed techniques consider not only rotating analysis but takes also into account the structural response of the machines.

Vibration, a key indicator
Uptime of large industrial rotating machineries is key for power generation as well as oil and gas industries. Vibration is a key indicator of the good health of these machines. It is important to be able to measure and understand what is going on regarding the vibrational pattern of these machines.
Rotordynamics diagnostics tools
For analyzing rotating machinery vibration, the following displays are key and will be discussed during the presentation:
- Scalar table: Gap, Overall, vector data (nX orders amplitude and phase), SUB1X, Smax
- Orbits (overall and nX), time blocks
- Shaft centerline and full shaft motion
- Frequency and order spectrum, waterfall
- Full Spectrum
- Trends, Bode and polar plots
- Raw signal and zoomed signal
A complete troubleshooting toolbox
It is key to be able to characterize rotating faults using methods described above. However, it is also necessary to be able to use other techniques to solve the full panel of issues. Of these techniques, common ones that we will be covering are: bump testing, ODS, modal analysis, torsional analysis, and multiplane balancing.
