SHAFT POWER, TORSIONAL VIBRATION &

GEARBOX ANALYSIS

with Omega software

Omega software was developed as a special tool for measuring and analyzing vibrations and shaft power.

The software works in two modes: data registration and data reading. Both modes have the same functionality, and there is only one difference: in the Data Logging mode, the program stores raw data files, and the Data Reading mode works as a “data player” with saved data files. Thus, you can choose which data should be stored during the measurements, and then replay it for more in-depth analysis.

Below are some screenshots that show the main functionality of the software.

Omega supports parallel measurements for 6 torque/speed channels and 16 vibration channels. The different sensors installation angles are used for phase analysis

Omega supports 4 types of gearboxes (trains 1 to 4). With a known number of teeth on the gears, it becomes possible to calculate the gear mesh frequencies (GMF)

The torque channel calibration page gives you complete control over the process, assess signal and noise levels

Real-time trends represent torque, speed and vibration channels. It shows power of the shaft, torque nominal, torsional vibration and torque pk-to-pk values

FFT/waveform analysis with different filters is available for both torque and vibration signals

Gearbox analysis page represents 3 graphs: Speed profile, Fourier Frequency Transform spectrum and bandpass filtered Waveform. The Waveform graph displays values for selected GMF (cursor on FFT spectrum) and each pulse represents a corresponding tooth on the gear

Cascade FFT analysis shows a trend of change for Fourier Frequency Transform spectrums

The polar plot demonstrates the behavior of the phase and its values depending on the shaft rotation speed. In other words, it demonstrates the movement of the "heavy point"

We use our own design hardware for measurements. This is 8-channels device for simultaneous measurements torque and speed.
