In the newest publications of many scientific papers the great interest in vibrations reduction and control can be seen. The authors show the huge significance of elaborating simple and effective methods of oscillations reduction [1-5]. The most important aplications of these vibration absorbers are impacting hammers, gas turbines, tubes in steam generators and their support plates, helicopter and weapon systems, ship trunks. Simultaneously the patricular interest in vibroimpact vibration absorbers can be seen. There are a lot of papers in which the authors show, that these kind of absorbers are more effective and work in wider frequency range than the traditional ones [6-12]. There are still no simple methods for elaborating the constructions of vibro-impact absorbers and confirming the parameters values for which the vibrations reduction has the practical significance. In this paper the new construction of the impact damper is presented. It is the first stage of elaborating such a damper. The range of effectivness of impact damper is shown. The new kind of discrette impact map is proposed. It is shown that using this map many aspects of kind of impacts, the energy flew and its dissipation, the reasons for chaotic motions existance can be concluded.
