Rotating Analysis

Fluid Film Bearings

ORBIGate, the OROS turbomachinery vibration solution, provides orbit, shaft centerline analysis, enabling to detect faults such as oil whirl and whip, preload, misalignement, rub and others.

Roller Bearings

The OROS FFT-Diagnostics module uses envelope demodulation to analyze these vibration sources to determine if the source is from the roller elements or the races.

Gear Analysis

Complex vibration signature due to high frequencies, is analyzed with the OROS FFT-Diagnostics tool, using cepstrum, kurtosis and harmonic markers.

Torsional Analysis

The OROS torsional software module utilizes a frequency to voltage converter for speed input providing the following information. The angular velocity profile displays RPM variations.

Balancing

The OROS Balancing module enables to unbalance quickly and accurately, displaying up to two planes.

Structural Dynamic Analysis

ODS (Operating Deflection Shape)

The ODS (Operating Deflection Shape) software module helps locating machinery and piping system deflection during operations. It is based upon simplified geometry description of the machine train.

End Winding Bump Testing

Generators and motors end windings are strongly excited by frequencies at twice the network frequency: any mode nearby that frequency will create high vibration response. FFT analyzers and the OROS Modal 2 solution are well adapted for bump tests acquisition, resonance frequency determination and deflection shapes.

Blade Modal Testing

When blade dynamic structural characteristics should be determined, they are submitted to modal testing: based on impact hammer testing or shaker excitation. Based on multichannel analyzers, vibration response can be captured by accelerometers or strain gauges. OROS Modal 2 can process the FRFs to give the modal characteristics.

Coupling & Transmission Analysis

OROS products like transfer functions, ODS, and damping calculations assist to start procedures.

Noise Analysis

Octave & Sound Intensity

The ambient noise generated from rotating machinery can be evaluated using general tools such as the 1/3 octave analysis, or using the sound power value and the sound intensity technique.
