Study of some complex frequency responses

To characterize a linear mechanical system, it is convenient to use complex frequency responses. The main ones are shown in Table 6 , although different authors use different names, and there is even a certain anarchy in the literature.

The most frequently encountered are impedance and its inverse mobility, receptivity and inertance, as they allow us to easily obtain the dynamic characteristics of the system, in particular resonance and antiresonance frequencies, the damping coefficient, etc. The methods used are based on certain analogies with electrical circuits. The methods used are based on certain analogies with electrical circuits. Although the fundamentals of these calculations have been known for a long time, they have only been further developed thanks to recently commercialized electronic measuring...
