Frequency Response Function- fundamentals

  1. Dec 2, 2011 #1
    I undestand the following concerning the frequency response function;

    Frequency response function is a fundamental measurement that isolates the dynamic properties of a mechanical structure.

    It describes the input output relation between two points of a structure as a function of frequency. Frequency response function is defined between a single input degree of freedom and a single output degree of freedom.
    Frequency response function is a measure of how much displacement, velocity or acceleration response a structure has at an output degree of freedom per unit of excitation force at an input DOF.
    Frequency response function is defined as a ratio of Fourier transform of an output response divided by the Fourier transform of the input force.

    Now;

    The inverse of Frequency response can have a name as:
    Compliance <-> (displacement/force)


    My questions are;
    1) Can anyone provide more insight into FRF (Frequency repsonse function)? Its significance?
    2) Also, what is the significance of the inverse of frequency response - Compliance?

    Please help

    Vishal
