Under the external influence of periodic forces and movements, forced vibrations are excited in a oscillating system. This case, which is significant in practice, occurs on the one hand on the objects to be measured, e.g. components, vehicles, foundations, buildings, etc., and on the other hand vibration transducers themselves can also be oscillating systems. Thus, these considerations form the basis for the planning of measurement tasks and the understanding of their results. Basic terms as well as the concept of transfer functions are developed on the basis of spring force excitation. The representation in the Bode and Nyquist diagrams is explained, followed by a discussion of other types of excitation.
