|Abstract: ||Background: Laser Doppler vibrometry is now a well established technique enabling noncontact
vibration measurements in the most challenging of environments. Rotor vibration
measurements are often highlighted as a major application of Laser Vibrometers due to their
non-contact operation and inherent immunity to shaft run-out.
Method of Approach: In such measurements, resolution of the individual axial and torsional
vibration components is possible via particular arrangement of the laser beam(s). Resolution
of the radial or pitch / yaw vibration components, however, can only be achieved by essential
post-processing of the data from simultaneous orthogonal measurements.
Results: This paper describes the principle and rigorous examination of a novel, dedicated
resolution algorithm enabling, for the first time, real-time post-processing of the outputs from
standard commercial instruments.
Conclusions: The system performed well, even in the presence of noise and other typical
measurement errors, and was implemented successfully in an engine vibration study.|
