More experimental modal analysis

  1. Feb 18, 2008 #1
    I'm trying to use experimental modal analysis to determine the modal parameters of a beaker. I'm using a shaker and have successfully obtained FRF's (I think!) Has anybody got any idea what i've to do from here? I've read what feels like a million articles but can't figure out how to actually extract the modal parameters! i'm supposed to be using the circle fit method if possible but i'm so so confused. Thanks to anyone who can help.

    Are you trying to determine the modes of the beaker itself, or a liquid inside of it?
