1 Introduction By suppressing unwanted vibrations in real life applications, significant improvements can be made in increasing safety and reducing discomfort for the passengers of an airplane, spectators on a stadium or construction workers on a bridge. Vibrations can be mitigated passively by means of tuned mass dampers that increase the mass and stiffness of flexible structures [ 1 ], or actively by means of sensors and actuators. Many active control algorithms have been developed and the efficiency of the closed loop system depends on the chosen

1 Introduction We study a model problem describing vibrational resonance [ 12 ] by means of the high-order averaging technique introduced in the series of articles [ 5 ], [ 6 ], [ 7 ], [ 8 ] (see [ 15 ] for a summary). In devices with vibrational resonance [ 12 ], [ 2 ], [ 16 ] the response of a system driven by a low-frequency forcing may be enhanced by the presence of high-frequency vibrations of suitable amplitude. Such devices feature in several current applications, including energy harvesting [ 9 ], [ 10 ], where the aim is to exploit the energy

motions. Behavior of each system where the body collisions take place is different, and therefore, each of them must be investigated in an individual way. Because of the practical importance, a good deal of attention is focused on analysis of vibro-impact systems, where the vibrations are governed by the momentum transfer and mechanical energy dissipation through the body collisions. This is utilized for impact dampers applied to attenuate high-amplitude oscillations, such as those appearing in subharmonic, self-excited and chaotic vibrations. Problem of the body
