DS-2000 Frequently Asked Questions

For rotating machinery, such as engines, turbines, and centrifuges, which must cover a wide range of rotational speeds from low to high, resonance between the rotational speed and the natural frequencies of each component that makes up the machinery (such as the rotating shaft, cover, and brackets) becomes the most troublesome problem.

In that case, it is necessary to analyze the relationship between rotational speed and vibration/sound level meter levels by varying the rotational speed, rather than measuring vibration and sound level meter levels at a constant speed. Tracking analysis provides important data for graphing the fluctuations in vibration and sound level meter levels due to rotational variations and helps analyze the resonance rotational speed (danger speed).

As seen in the figure below, the rotational speed and spectral line diagram (3D representation of the spectrum) is a chart that intuitively captures the changes in the frequency (order) spectrum in response to changes in rotational speed. In contrast, the rotational speed tracking analysis clearly indicates which harmonic components are resonating at a specific rotational speed in a 2D graph. Graduo can perform tracking analysis during measurement as well as offline tracking calculations. Additionally, real-time octave band tracking analysis is also possible.
