Example of rotation-tracking diagram of engine vibration



Example of data output by 3D mapping


This software enables tracking analysis with high-speed (calculation speed: approx. at 20msec/4-ch), high-resolution (maximum at 1000 blocks) and high-accuracy (more than 100dB dynamic range). Each model has V, W and X at the end of model name according to its number of channels. DS-0222VA is available for 2-ch, DS-0222WA is for 4 to 8-ch, and DS-0222XA is for 10 to 32-ch.


It can plot rotation-tracking diagram during calculation, and also can set and plot the diagram of intended order or frequency after calculation. If you file a 3D display data, you can read the file in order to plot its rotation-tracking diagram later. Also, campbell plot can be plotted as an option. Windows (Windows XP/VISTA/ 7 ) is applicable as an operating system.


*DS-0221A Series FFT analysis software is required to perform tracking analysis.

What is Tracking analysis

Rotational machines such as engines or compressors etc. are rotating with wide range of rotational speed from low to high speed. For those rotational machines, resonance between rotational speed and natural frequency of each component (rotational shaft, gear, bracket etc.) of rotational machine may be causing serious problem. As an example of torsional vibration including large generator, resonance may generate excitation energy lager than allowable stress, and therefore it causes serious accident to destruction. Rotation-tracking analysis helps greatly to observe the cause such as which component or order of rotational speed makes noise and vibration when a rotational machine makes vibration with certain rotational speed. As shown in the below, rotation-spectrum diagram (3D spectrum) figures out the change of frequency (order) spectrum respect to the change of rotational speed. In comparison, rotation-tracking analysis (order tracking analysis) shows that how much noise and vibration are generated from which order of rotational component with two-dimensional graph.

*Rotational order is defined that a based rotational speed is 1-order, n-times rotational component is n-order. Data analysis with order on the X axis and amplitude on the Y axis is called rotational order ratio analysis. Rotational order ratio analysis requires rotational signal information.
