Abstract

This paper presents coupled structures based on a nonlinear hysteresis friction damper subjected to harmonic forces for vibration suppression. The steady-state responses of the structures are obtained by the Runge–Kutta method and the harmonic balance method, which describe the hysteretic nonlinearity of friction dampers and exhibit their attenuation performance. The forced response is well controlled by the normal force applied to the friction damper, and the amplitude and frequency of the resonance peaks can be varied within a certain range by changing force magnitude. The time-averaged vibrational power is calculated to show the total input power and power dissipated by each element. The results indicate that the friction damper participates in the energy dissipation in the frequency band around the resonance frequency, thereby enabling high-amplitude vibration filtering. The vibration power flow analysis shows that the normal force for the friction element can be designed to reduce vibration transfer. These results confirm that such friction dampers have the potential to be designed to be adjustable and meet different vibration control objectives.
