    magnitude of acceleration FRFs

    Thank you IRstuff, my question was about converting from FRF acc to FRF disp. (2*pi*f)^2 can be still applied in this domain. as far as i know this relationship is for frequency domain of the acc and disp. so i was wondering if i still could use that for FRFs??? Best regards,

    magnitude of acceleration FRFs

    Thank you for your response, actually i just found out that the formula i was using for converting acc. FRFs to disp. FRFs might be wrong. do you have any idea what is the right relationship between these two?? thank you very much

    magnitude of acceleration FRFs

    Hi all, I have got the magnitude of acceleration FRFs of a real test and no complex numbers. i need to have displacement FRFs to calculate PSD of the response displacement. in order to obtain the disp. FRFs, the acc. FRFs need to be divided by (w^2), w is the related circular frequency. the...
