The paper analyzes methodology for investigation of dynamic characteristics of heterogeneous systems: honeycomb optical tables and pipelines with sediments, applying mechanical impedance. The developed methodology may be used to assess the quality of plate or cylindrical heterogeneous structures, according to the dynamic characteristics and parameters established in the methodology. It was shown that impedance characteristics are informative to determine some parameters of the quality of honeycomb optical tables and are correlated with the thickness of the pipe's inner sediment layer. Therefore it is possible to choose typical resonance frequencies and according to their changes, the decision about inner layer presence and its value can be made.
