Looking for modal analysis software for ground vibration tests

[Rexbo]

I'm looking for Labview code or compiled program that will work with a NI/VXI data acquistion system and supports modal analysis of ground vibration test data on airplanes. Specifically, based on accelerometers, need to synthesize mode shapes; mode indicator function; stabilization diagram; damping estimation; mode animation; mode overlay (comparison); Modal Assurace Criteria (MAC); plotting.

I would look at the sound and vibration toolkit. This is the leading analysis package for vibration analysis. http://sine.ni.com/apps/we/nioc.vp?cid=3122〈=US

LabVIEW and our dynamic signal acquisition products, particularly the NI 4472B have been used extensively for acquiring data from GVT on aircraft.

For conducting the analysis that you describe, there are several good solutions from some of our partners. These include MTS I-DEAS, m+p International Smart Office, and Vibrant Technology's ME'Scope. All of these packages directly support the NI 4472B as a front end. MTS recently delivered a system to KARI for a high channel count GVT test that used the NI 4472B as the front end.

MTS is developing a new package based on LabVIEW for doing this type of testing, but won't be available until sometime later.

Currently we are using the SCXI modular system and we wish to perform modal analysis and in particular with the I-Deas Test, formally MTS, software environment.  Does I-Deas Test have drivers or the capability to utilize the SCXI hardware for modal testing?

Quartus,

If the device drivers you are looking for are not available at the link below, you may want to try contacting the manufacturer to see if they have developed anything.
