The solution of a number of researches and practical tasks on the topic of oscillation suppression is considered. The relevance of the theme is confirmed by the fact that many constructions (from car designs to multi-storey buildings) are subjected to the greatest and undesirable oscillations, i.e., resonance. A patent review of various vibration damping systems has been completed. The laboratory experiments have been carried out and, based on their results, the necessary calculations have been made for determination of the vibration characteristics of single-mass and two-mass systems. The results showed that an effective way to shift the position of the resonant frequency is to increase the mass of the load of the dynamic damper. This conclusion is a prerequisite for the development of ways to control the cargo mass.
