WebA Frequency Response Function (FRF) gives insight into a structure’s natural frequencies, damping, and mode shapes. Often, the FRF is displayed with units of acceleration (g) over units of force (N) resulting in an accelerance unit of g/N. However, there are alternative formats with which the FRF can be displayed ( Figure 1 ).

WebAcquisition of the frequency response function (FRF) from the disturbance source to the sensitive payload is one of the most crucial stages in integrated modeling, and many scholars have worked hard on this [20,21,22]. It is challenging to measure the FRF directly due to the restricted room for RWA installation in real spacecraft, particularly ...
