Viewing Operational Deflection Shapes (ODS) from a Gas Turbine Generator

Viewing Operational Deflection Shapes (ODS) from a Gas Turbine Generator

As its name suggests Operational Deflection Shape analysis shows the vibration pattern experienced during normal operational condition. This is different to other structural vibration tests such as impact hammer tests, bump tests or shaker tests which require a more controlled excitation force and are used to determine specific characteristics of the structure under test, such as natural or resonant frequencies.

Bearing & Gearbox Vibration Analysis Using Demodulation Techniques (Part 1)

Bearing & Gearbox Vibration Analysis Using Demodulation Techniques (Part 1)

Bearings and Gearboxes are fundamental components of rotating machines and are used in many industrial applications. These are critical components and as such any failure can prove expensive in both repair cost and down-time. Because of this condition monitoring has…
