| Abstract: |
| The effects of the rubber layer thickness and bolt torque on the mechanical properties and fatigue resistance of the rubber friction damper were investigated.The results showed that，the initial displacement，initial damping force and friction load of the rubber friction damper decreased with the decrease of the rubber layer thickness. With the increase of the bolt torque，the initial displacement of the rubber friction damper changed little，the initial damping force and friction load increased first and then decreased. When the bolt torque was 400 N·m，the initial damping force and friction load were at the maximum. Before and after fatigue test，the friction load-sliding displacement hysteresis curves of the rubber friction damper showed that the damper had good energy dissipation capacity，indicating excellent fatigue resistance. |
