Hello, 
I'm a PHD student and I work on operational modal analysis.
Actually, I want to use LMS TEST LAB V13.


Firstly, I want to know what is the tool that let me to measure time reponse of a structure which is excited by an operational excitation.


Then, afert having these temporal measurements, I would like to use the operational modal analysis tool on LMS, to identify the model parameters of my struction by only output data identification.


So, is there any tutorial for the tool "operational modal analysis of LMS TEST LAB V13?
Thank you for your help Smiley Happy

Hi Asia,

First you'll need signature acquisition with time recording add in to record the throughput data.  Once you have the raw data, then you can use "operational modal analysis" to calculate cross power and extract mode shape.  Can you send me a prive message here with your email address?  I can send you the tutorial.
