performing a modal analysis and plotting an frf

[Vishal2588]

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

The Fundamentals of FFT-Based Signal Analysis and Measurement in LabVIEW and LabWindows/CVI 

Modal Analysis in LabVIEW

Two-Sided, DC-Centered FFT

Fast Fourier Transform (FFT)

Please let me know if you have any questions.
