Let us consider a complicated mechanical object. For the study of its vibrational field it is sufficient to use a certain dynamic model. Theory of a medium with complex structure can be applied to this effect. The properties of the real object can be reflected in the medium with complex structure, the medium parameters are determined by rigidity and mass characteristics of the object resulting in certain integral characteristics and spectra. This enables one to avoid too much detailization of the object structure. The application of the theory of a medium with complex structure results in obtaining some generalized characteristics of the vibration field.
