Design and Mechanical Characters Study of a Self-Feedback-Friction Damper
To meet the vibration control needs working in varied vibration conditions, a new type of semi-active controllable friction was developed in this study, called Self-feedback-friction Damper, with the control of the feedback signal of vibration amplitude. Through calculation and analysis of its work capacity, the parameters of the Self-feedback-friction Damper are determined. The research shows the damping force of new friction damper changes to adjust the varied displacement, to obtain a better damping effect, controlled by the signals of the vibration amplitude.
