Campbell analysis for blade vibrations

[norton]

Hi,

I would like to program a Campbell analysis system in LabView 6.1. Has anybody experience in this issue ?


Thanks for your help

Thanks for your question. I believe there are two parts to the answer to your question. First, the analysis behind the displays - tracking orders, magnitudes, and phase of the blade vibration signals. (as a side note, I am interested in learning about the sensors and daq hardware you are using). The second part is the display.

With my activities in rotating machinery data acquisition and analysis, we are enhancing the NI toolsets with examples and built in components or order analysis, fft analysis, and display in campbell diagrams. We have a current customer request and expect to have a summary document describing several ideas to address the campbell plot. I'll make another entry to this forum later this week with the suggestions.

Thanks again
for your question. Let us know if you can provide more details about your requirements.

Sincerely,

I have two base solutions for campbell diagrams. 1st is using an xy plot, and the second is using a picture control toolset. Let me know if you would like to review these.

Sir,

I have planned to use Campbell analysis for Vibration Analysis of Gas Turbines. You have given two solutions. In that I need to know more details regarding Picture control implementation in LabVIEW.

Thanks,

I would to see your results for implementing a Campbell Diagram in LabView.
