Advanced vibration analysis

Root cause troubleshooting

Troubleshooting rotating equipment and structural installations can very complex and not easy to comprehend. The vibrational behavior may indicate damaged components, but also operational behavior which is at the root cause of these component degradations. By measuring the Operational Deflection Shapes (ODS), structural malfunctions responsible for several drivetrain failures (e.g. bearing problems) can be elucidated.

As the ORBITS team is certified as ISO 18436-2 Category IV vibration analysts, we have gained thorough knowledge and experience able to diagnose general rotating equipment up to turbomachinery.

Operational Deflection Shape - ODS

The operational motion analysis of structural deflection can be assessed through an Operational Deflection Shape analysis (ODS) in order to find proactive solutions in solving structural weaknesses or excessive vibrations. Additionally, an easy relation between component failures and machine operational motion can easily be found.

If any resonances are occuring, ODS analysis can pinpoint the exact adaptions needed in order to avoid any mode shape excitation to interfere with the operational machine behavior. If not possible, the resonance ranges and corresponding mode shapes may as well be mapped in order to program an operational speed area to be avoided.

Experimental Modal Analysis - EMA

Through an Experimental Modal Analysis (EMA), a full range motion analysis of structural deflection can be mapped and visualized in order to find the areas of resonances and other characteristic properties (stiffness/damping) for every corresponding mode shape.

By synchronously capturing force and vibration data on structure, the mode shapes of the scoped structure can be assessed and visualized. Understanding the data content in the structural excitation and simultaneously evaluating the data content in the structural response enables the full analysis of the system in between. These insights can gain new engineering approaches to avoid operational issues related to undesired excitations of structural motions.
