Investigating Application of Nonlinear Semi-active Impact Dampers for Suppressing Forced Vibrations

In this study, the effects of utilizing a vibro-impact electromechanical device to suppress undesired vibrations are investigated. The demonstrated vibro-impact system serves as a vibration suppressor and provides the necessary energy for its sensors and control components, making it a potentially autonomous system. The electromechanical equation of motion for the system under examination is calculated and experimentally verified. Also, the effect of adjusting the gap size, a crucial parameter of the Vibro-impact system, on its electromechanical performance of the system is investigated. Additionally, the effectiveness parameter is announced as a parameter that results in enhancing the energy harvesting and vibration-suppressing capabilities of the demonstrated vibro-impact system. Finally, it is demonstrated that the characteristics of the electromagnetic vibro-impact system can be tuned as an effective autonomous semi-active impact damper system.
