Visual ODSTM Use Example
A blower fan located on the roof of a building was experiencing severe vibration, throwing off belts, and creating high noise and vibration levels throughout the building. All attempts to balance the fan had not solved the problem.
A set of ODS data was taken while the fan was running, using a 2-channel analyzer with a tachometer signal. A set of Peak & Phase data at the operating speed of the motor was acquired. The animated ODS showed that the base of the motor at the end opposite the belt was moving out of phase with the motor. Removing some paint from the base of the motor revealed a previously undetected crack in the motor mount. After repairing the crack, the fan was re-balanced and the severe vibration and noise problem was solved.
ODS – Videos
Using the same technology that robotic vision and autonomous vehicle companies utilize to detect objects in motion, MEscope ODS Videos™ accurately measures surface vibration from a high-speed video recording. Using accurate time waveforms or frequency spectra extracted from the video, all of the time-tested features of MEscope can be used to document the vibration.
With the MEscope ODS Videos™ package, you can post-process the time waveforms or frequency spectra extracted from a vibration video recording, and record clear color videos of the ODS animation. You can also store the time waveforms. frequency spectra, ODS’s & videos in a machine-based archival database.
