Using this option you can carry out order tracking for speed-dependent oscillations. During order tracking the oscillation signals measured at a certain speed are subjected to a Fourier transformation (FFT). Individual spectral lines are taken from the spectrum where the frequency corresponds to a multiple of the base frequency as determined by the speed.
The FlexPro Order Tracking option can process data in different data structures. You can either enter multiple individual signals that are measured at specified revolutions or one ramp-up signal and the synchronicously measured speed signal. FlexPro can analyze time and angle (phase) signals. The speed signal can also be interpreted as an impulse signal.
The result of the order tracking is a 3D data set with the amplitude plotting respectively, against order and frequency or speed. With the Split Orders Analysis Object, you can divide the result into several 2D data sets, one for each order. You can use the Family of Acceleration Hyperbolas Analysis Object to compute a 3D data set of acceleration hyperbolas to be displayed in the result diagram for order tracking.
Features
