Identifikation of rotating systems

[RRapha]

Hello,

i want to estimate a modell from time data. Thus my test-stand rotates with 3000U/min the

model is estimatet with a high peak at 50hz. If I bandpass the timedata from 60hz on

the estimation also goes bad. Does anybody has an idea how i can ignore the 50hz??

Greetings,

RRapha

Hi,

for analysis of rotating systems, order analysis would probably be a good choise. See the following link for more information:

The LabVIEW Sound and Vibration Measurement Suite or Toolkit offers a lot of functions to perform different analysis of your signal:

Please provide some more information about your measurements, to figure out a function that fits to your problem. If you just want to extract an area from your measurement signal, the standard functions for signal processing or the array functions in LabVIEW should be sufficient.

regards,
