Getting Started with Modal Analysis in LV

[MickeyD]

The folder here contains a VI palette that gives you the basic building blocks for Modal Anlaysis.

Several pieces of NI software need to be installed before you download this palette. They are:

LabVIEW 2009 or later.

Sound and Vibration Measurement Suite 2009 or later

System Identification Toolkit 9.0 and later

Installation Instructions

1) Exit out of LabVIEW if you have it open. If it is already closed do not open it.

2) Download the Modal Analysis folder and save it in your user.lib folder for LabVIEW. The image below shows what it might look like on your machine.

3) Close the user.lib directory and start LabVIEW.

The VI pallette should be in your User Libraries. The following image highlights what it should look like.

Greetings pswalunj!  We'd be glad to further assist you, however this isn't the best medium to do so.  Please either contact your NI local support or post to our discussion forums, and someone will be glad to help out.  Feel free to reference back to this example, and further detail what problem(s) you're running into.  Thanks!

Ok. Thanks sir for your Quick and positive response.

Hi, 411051

We don't have much monitoring of this space for answering your questions. I would recommend posting to the discussion forumns.

Thanks

Hi, I run the examples in this module and it seem good. But there is no example using MP_SSI VIs. Could you please send me some example using that VI? Thank you!

Hi~

  it is not able to start the Modal analysis.vi, because the program lacks the  si_Estimate Model_input FRF format adjustment (SISO).vi.

I am appreciated to hope you to supplement the SISO.vi.    Thank you very much.
