Rotation machines such as engine or turbine/centrifugal machine, etc. are rotating with wide range of rotation speed from low to high speed. For those rotating machines, resonance between rotation speed and natural frequency of each component (rotation shaft, cover, bracket etc.) of rotating machine may be causing serious problem.

 

In this case, it is necessary to analyze the relation of rotation speed and vibration/noise level not in the constant rotation speed but in the fluctuating rotation speed. The tracking analysis provides very important data to analyze resonance rotation speed (critical speed) by making the graph of the fluctuation of vibration and noise level caused by the fluctuation of rotation speed.

 

As shown in the below, rotation speed and spectrum diagram (3D spectrum) figures out the change of frequency (order) spectrum respect to the change of rotation speed. In comparison, rotation speed-tracking analysis (order tracking analysis) shows that how much noise and vibration are generated from which order of rotation component with two-dimensional graph. The DS-2000 can be performed tracking analysis while measuring. Also, it can be performed the tracking calculation in the offline state and tracking analysis of the real-time octave band.
