I am looking for Modal Analysis Labview VI lib or example?

I am looking for Modal Analysis Labview VI lib? specifically, I conducted Frequency Response Measurements, I managed to construct the experimental frequency response function. Now, I am looking for modal extraction from the experimentally determined frequency response function.
I appreciate if someone knows about Labview VI or example to perform the curve fitting in the frequency domain to extract the modal parameters.
Thank you in advance.
Atef T. Massoud

Atef,
I found the following paragraph in the on-line description of the Advanced Signal Processing Toolset for LabVIEW:
<>
"You can also construct your own custom applications in LabVIEW with a VI library of the most efficient and common algorithms such as covariance, principle component auto-regression (PCAR), Prony's method, and the matrix-pencil method. Some of these methods have not been commercially available before the release of this toolset. Using these VIs, you can perform both super-resolution analysis and modal-analysis. Moreover, VIs provided can easily be tailored for many other signal analysis applications, such as system identification and linear prediction."
It seems as if this set of tools might
help you with your application.
I hope this suggestion gets you pointed in the right direction. Have a pleasant weekend.

Looking for modal analysis software for ground vibration tests

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.

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.

Frequency response function modal analysis

After reviewing the signal analysis functions in DIAdem I have realized them to be a bit limited for modal analysis. I have a couple hammer impact tests that I need to process a frequency response function for, and since this is brand new to me I'm not seeing anything in the embedded function list that is going to help me. I was wondering if anyone out there has a couple of pointers on generating a FRF plot for modal hammer impact tests. I did notice that the ChnFFT2 command allows me to generate a transfer function, coherance, and FFT Cross Spectrum channels for analysis. Though I might be confused and this may be everything I need. My FFT2 settings are below.
[code]
FFTIndexChn      = 0
FFTIntervUser    = "NumberStartOverl"
FFTIntervPara(1) = 1
FFTIntervPara(2) = 2500
FFTIntervPara(3) = 1
FFTIntervOverl   = 0
FFTNoV           = 0
FFTWndFct        = "Rectangle"
FFTWndPara       = 10
FFTWndChn        = "[1]/Time axis"
FFTWndCorrectTyp = "No"
FFTAverageType   = "No"
FFTAmplFirst     = "Amplitude"
FFTAmpl          = 1
FFTAmplType      = "PSD"
FFTCrossSpectr   = 1
FFTCoherence     = 1
FFTTransFctType = "Spectrum H0"
FFTCrossPhase    = 0
FFTTransPhase    = 0
Call ChnFFT2("[1]/Time axis","'[1]/H_1' - '[1]/H_4'","'[1]/A_1' - '[1]/A_4'") '... XW,ChnNoStr1,ChnNoStr2
[/code]

Standard modal analysis has something denoted as FRF. I have a labview application note "The Fundamentals of FFT-Based Signal Analysis..."
Frequency Response Function
The frequency response function (FRF) gives the gain and phase versus frequency of a network and is typically computed as
where A is the stimulus signal and B is the response signal.
The frequency response function is in two-sided complex form. To convert to the frequency response gain (magnitude) and the frequency response phase, use the Rectangular-To-Polar conversion function. To convert to single-sided form, simply discard the second half of the array.
You may want to take several frequency response function readings and then average them. To do so, average the cross power spectrum, SAB(f), by summing it in the complex form then dividing by the number of averages, before converting it to magnitude and phase, and so forth. The power spectrum, SAA(f), is already in real form and is averaged normally.
Refer to the Frequency Response and Network Analysis topic in the LabVIEW Help (linked below) for the most updated information about the frequency response function.
http://zone.ni.com/devzone/cda/tut/p/id/4278
So the options for FFT2 are
No
DIAdem does not calculate a transfer frequency response.
Spectrum H0
DIAdem calculates the transfer frequency response by dividing the FFT of the output signal (A) by the input signal (E): FFT(A)/FFT(E). DIAdem averages the amplitudes of the individual transfer functions.
Spectrum H1
DIAdem specifies the cross spectrum and the auto spectrum for each signal pair. DIAdem calculates the transfer frequency response by dividing the averaged spectra: Middle(cross(A,E))/middle(auto(E)). DIAdem does not average phases, because phases can delete each other.
Spectrum H2
DIAdem specifies the cross spectrum and the auto spectrum for each signal pair. DIAdem calculates the transfer frequency response by dividing the averaged spectra: Middle(auto(A))/middle(cross(E,A))
If you assign the values Spectrum H1 or Spectrum H2 to the variable FFTTransFctType, DIAdem averages and divides the cross spectra and the auto spectra and calculates the amplitudes last.
Which state auto spectrum when FRF is power spectrum.

Valid Frequency Domain Analysis ?

There seems to be two issues with using the MyDAC for frequency domain analysis ( Bode Plots etc. )
1) The system does not employ Anti-Aliasing Filters . This can create major frequency fold-back problems.
2) The analog inputs are multiplexed which leads to a channel to channel phase error .. up to 180 degrees at the Nyquist frequency.
Is there any 'behind the scenes' processing done to mitigate these issues ??
Thanks in advance
Solved!
Go to Solution.

Hello ProfP,
Thanks for the post! Sorry to leave you hanging for so long. I have some answers for the 2 points you asked about above.
1. You are correct, the myDAQ system does not employ Anti-Aliasing Filters. The ELVISmx Bode Analyzer artificially limits the input frequency when using the myDAQ to 20 kHz. At that frequency, you
only get 10 points per period from both the AO and AI.
Anti-alias filters behind the multiplexer would slow down settling behavior, so they were not included. You can add filters in front of the multiplexers (at the AI0 and AI1 pins). I'd recommend they be buffered, though. Charge injection on the multiplexer makes high speed scanning very sensitive to source impedance. Note the effect in the Settling Time versus Different Source Impedance figures (21 and 22) of the myDAQ manual: http://www.ni.com/pdf/manuals/373060b.pdf
2. You are correct. Two-channel acquisitions are phase-skewed by the 1/(2*scan rate) when the scan speed is faster than 40 kSps/ch. For example, if you acquire at 200 kSps/ch, the interval between consecutive measurements on AI0 and AI1 is 1/(2 * 200 kHz) = 2.5 us. Below 40 kSps/ch, the phase skew is constant at 12.5 us. This is intended to help very slow acquisition rates appear more like simultaneous acquisitions rather than keeping 180 degree phase skew unnecessarily. These are default configurations. You can adjust the conversion interval parameter through the DAQmx API if you prefer to customize the behavior.
Let us know if this is the information that you needed and thanks for using NI myDAQ!

Octave analysis of frequency domain data in SVT

Hello!
How can I make the octave analysis of frequency domain data in Sound & Vibration Toolkit?
Thanks,
Alfrednovi

Hi!
To make the octave analysis of frequency domain data you have to pass in your time domain data to the Octave Analysis VIs. The time domain data will allow you to window the signal using the correct values.
The Sound and Vibration toolkit has several examples that show how to do this. You can find them under Help>>Find Examples and then browsing to Toolkits and Modules>>Sound and Vibration. This directory has Traditional DAQ and NI-DAQmx examples as well as Octave and Third Octave analysis.
You can also look for other examples using the Example Code Library.
Good Luck,
Tica

Frequency domain analysis

Does photoshop offer frequency domain analysis of an image?
The standard way to remove noise, i.e. background spots, is do spectrum analysis and remove those high-frenquency signal. Is photoshop image-> adjustment -> level a frequency analysis?

NR not very trivial. IMO anyway.
I had much the same questions when I moved from frequency domain to time domain. A strong preparation in analog engineering treated time domain sparsely, particularly noise. We dealt with detector noise in a nuclear physics lab by running the detectors in pairs at cryogenic temps. The detectors were connected to a coincidence circuit (and gate to you digital folks!). Even then, the output of the gate had to be carefully amplified, then subjected to an A to D converter where the output was displayed as a histogram. I'm sure things have progressed mightily since then, (ca 1950's).
I used the coincidence idea back about 2004 or so when I needed an image absolutely as noise free as possible by shooting the object (an exposed wooden frame for a building constructed from Port Orford Cedar.) twice, then constructing a curve applied to each image to allow adding them together to match the colors and values of a single shot. Extended versions of PS now allows this without any curve inventions!

Is it possible to make a Frequency Domain Reflectometer using LabView? For waveguide frequency measurement?

Hi everyone
I have a tricky question that I have looking around for the answer but couldn't find it!
I want to know if I can build a Frequency Domain Reflectometer (FDR) to measure frequency return in waveguide. Telecommunication engineers would understand what I mean! It a bit like TDRs but its frequency instead of time.
I would like to build a Frequency Domain Reflectometer using labview application, how can I do that? What sort of code do I need and what equipment do I need to operate with the NI code?
Please give me the chance to thank you all very very much for your help and support and for looking here,
regards
Fezz

Hi Fezz,
I am not familiar with using FDR systems but know there is a good example of producing a TDR in LabVIEW available on the community. This might provide you with a base and a grasp of the architecture you could use to create the functionality.
Time-Domain Reflectometer (TDR) Example
Regarding the equipment you would require to achieve this I strongly recommend contacting your local NI office who will be able to adviser you fully as this will depend upon your desired specification.

Frequency domain in dsp module with speedy-33 target

Hi,
I am using the speedy-33 to generate a sine wave, square wave, sawtooth wave, and a ramp wave. I am doing an FFT analysis on them to display the signals in the frequency domain. However the x-axis displays the sample number for both the time domain and frequency domain. Is there a way to moake it so the x-axis is displaying either the time in the time domain or frequency in the frequency domain.
Thanks for your help.

Hi Rcarr,
I'm a little confused as to what time data you expect to see? The signal you are generating is just and array of numerics, but there is sampling information used to create that signal. Do you want to have the signal start at 0 and display the time that has elapsed?
In short, you can't do this within a VI running on the Speedy-33. However if you pass data to a host VI then you can manipulate the graph. You can do this by calculating a multiplier for the x-scale of your graph based on the dx of you sampling. There is a property node for the graph where you can set this multiplier but you can only use it on a host VI not running on the Speedy-33.
If you use the Simulate Signal Express VI you will have to create a constant that is the same value as the property you specify within the properties. You might consider using the EMB sine wave.VI that has an input for sampling rate and number of samples. You can then take the reciprocal of the sampling frequency and run that to the multiplier input by passing it to your host VI.
Let me know if I can help any further or if you have any questions.

UFF in frequency domain

Hello,
I'm new in Labview. I'm trying to extract data from a Frequency Response Function to a UFF file. I know there is an example in the "Sound and Vibration toolkit" but is to extrat data from time waveforms in the Time Domain, but I wanted to extract data from the Frequency Domain.
Could anyone help me?
Thanks,

Predictive Algorithm for Churn analysis

Hi,
Can anybody help me with the algorithm which I can use for churn analysis?
Thanks,
Atul

Hi Atul,
For Churn analysis or what is usually referred to as a binary classification problem where the customer is either staying or leaving=churning I would suggest one of the following algorithms:
CNR Decision Tree - which also provides a decision tree to explain which feature split is influencing the target (churn) the most.
You could also chose one of the R based Neural Network algorithms, however the produced predictive model & results are usually hard to explain.
If need be you can enhance the number of available algorithms by adding you own R functions - there are a lot of examples in this community.
If you have SAP HANA you could also chose:
Decision Trees:C4.5, CHAID or CART (new in SAP HANA SP08).
Other supervised learning algorithms for binary classification: Naive Bayes or SVM (Support Vector Machine).
There are a lot more but this should get you started.
Best regards,
Kurt Holst

Getting Eigenvectors of a large array for PCA analysis

Hi,
I am writing code for PCA analysis based on Karhunen-Loeve decomposition. This involves getting eigenvalues and eigenvectors of a very large array i.e. 944x944. I'm getting the error -20062 which indicates that I have exceeded the maximum iterations of this VI. Does anyone have a suggestion as to what I may do from here, besides using different software, or is this my only choice? Thanks in advance.
Marion

This code looks like mine except there are no default values on the 2d array. It is behaving really strange. In LabVIEW 6.1, I created a two nested for loops and added their i's to create the 945X945 matrix. The first time I ran the code, it did not return anything. The second time I ran the code, I hooked up the error output and closed down the windows for "eigenvalue and vector.vi" and it worked!! I saved for previous and the code worked in LabVIEW 6i. I am not sure what is causing the problem.

Numerisation of Acquired Data and Transforming into Frequency domain to process it with some mathematical expressions

Hi everyone,
I've been trying to manage some signal processing stuff, I use mathscript node for it; due to the node, i have to transform the data set into numerical values. Due to my research, i should do my processing in frequency domain.
I did a VI, but i dont think it will work properly when i will use it with acquired data. The VI in the attachment has four dummy-signal sources, sines, consider these as analog input channels. The main question is actually how to process acquired data with numerical operations. And how to properly transform the time domain series into "numerical" frequency domain array.
Take a look at the example in the attachment. The other one is mathematical expression of the process.
Thanks,

Digital Watermarking on image in frequency domain

I am working on a Project which aims at studying the digital watermarking on image, with both spatial domain and frequency domain.
I have finished the spatial domain but is frustrated with the frequency domain right now. I have no idea on how I can possess the frequency domain of a image. Is there a built-in function which can help us to do so?
Thank you for your help.

Performing a modal analysis and plotting an frf

Hi,
I am carrying out a modal analysis on a composite plate. I am using a shaker to excite the plate. I have two accelerometers - one fixed over the shaker for the input signal and the other fixed to the plate for the output signal. I would like to carry out a modal analysis and observe the FFT or the FRF for this plate. I am pretty new to Labview and would like some advice on generating the FFT or the FRF plot and observe the peaks.
Thanks.

Hi,
According to your question I have the following information for you:
Please have a look at this documentation. With this information you should be able to use signal analysis in Labview
