Order Tracking
Option
 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 analyse
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
- Source data may be sampled based on time or angle.
- The factor to transform time into RMS can be specified.
- The speed signal can be specified as an impulse signal. The number
of impulses per revolution can be specified.
- When analysing ramp-up signals, the speeds can be specified or read
from an external data set.
- When analysing individual measurements, the associated speeds can
be specified directly or computed from additional signals by averaging.
- Adjustable FFT-length.
- FFT spectra amplitude, amplitude2, RMS, MSA, complex, real part, imaginary
part, phase.
- Taper windows rectangular, Hamming, Hanning, Bartlett, Kaiser-Bessel,
Flattop, Blackman, Cosine, Welch, Connes.
- Adjustable band with for detecting the orders .
- The list of orders to be analysed can be specified or obtained from
a separate data set.
- Order, speed, and frequency can be freely assigned to the X and Z
components of the data set result. An external data set can be specified
as the source for the X component.
- Splitting of 3D result into individual orders.
- Computing of a 3D data set to display a family of acceleration hyperbolas.
